Synthetic Diamonds



Synthetic Diamonds







The first synthetic diamonds were produced by General Electric in 1954. A synthetic diamond is basically a rock that has the durability, refractive index and hardness of a natural diamond – but it is made by man.

A synthetic diamond should not be confused with stimulant diamonds, such as glass, cubic zirconia, or moissanite.

Although the technology for synthetic diamonds came into play in 1954, no synthetic diamonds were ever seen on the market until the 1990’s. This was due to the fact that it took many years for General Electric to produce a synthetic diamond that could compare with the quality of a natural diamond – and when they figured out how to do it, they found that it cost more to produce a synthetic diamond than it did to mine and cut natural diamonds.

Finally, a small company by the name of Gemesis Corporation figured out a way to produce synthetic diamonds that were of the same quality as natural diamonds, at a cheaper price.

Today, Gemesis produces synthetic white diamonds, and colored diamonds as well. These diamonds sell for about 1/3 of the cost of a natural diamond, but there is a shortage of them, and they are hard to find. In fact, it seems that synthetic diamonds are rarer than natural diamonds!

Beryls - Emeralds and Aquamarines Diamond




Beryls - Emeralds and Aquamarines







The beryl is the family of crystal that creates emeralds and aquamarines, when its color is green or blue-green, respectively. Red beryl is bixbite or red emerald or scarlet emerald, pink beryl is morganite, white beryl is goshenite, and a clear bright yellow beryl is called golden beryl. Other shades such as yellow-green for heliodor and honey yellow are common. It can also come in violet.

The earliest known source of emerald was near the Red Sea in Egypt, the so-called Cleopatra's emerald mines. They were probably worked from about 2000 B.C., apparently the location of them was lost in the middle ages, and not rediscovered until 1818. Most emeralds used in ancient jewelry are believed to have come from these mines. They are not worked nowadays because of the low quality of crystals found.

Emeralds have been found in Austria since Roman times; these are no longer commercially mined.

Columbia is generally recognized as the source of the world's finest quality emeralds, both in the past and the present. The Columbian Indians were using them before 1537, when Quesada conquered Columbia.

Russia has been another important source of emeralds in the past. Emeralds were discovered in Australia in 1890 in New South Wales. Emeralds were discovered between1927 and 1929 in South Africa, followed by other sources.

Another important source of superb quality emeralds, usually only of small size, is in Zimbabwe formerly Southern Rhodesia. These were discovered only in 1956. Emeralds were known in India from antiquity, but their source is not certain. The quality of Indian emeralds is very variable, but most are polished as beads.

Other sources of emerald include Norway, North Carolina, Connecticut, Maine, New Hampshire, although none of these are very important. But if you're vacationing in any of those states, we best you'll keep your eyes peeled for any stray beryls!

Hooker Emerald

There's something incredibly mysterious about the largest emeralds. It's one of the rarest of gemstones, unattainable for most of us, at least in a good-quality stone. This magnificent 75.57-carat emerald was supposedly owned by the Ottoman Empire until 1900. Legend has it was used in the belt buckle of a sultan!

The stone was featured in Tiffany's 1950 Christmas Catalog. Mrs. Janet Annenberg Hooker bought the stone in 1955 from Tiffany's and donated it to the museum in 1977.

Emeralds are part of the beryl family of jewels. Green beryls are called emeralds, while blue-green beryls are called aquamarines. A pink shade of beryl is called Morganite. There's even a red beryl that's rarer than emeralds themselves.

The name emerald comes from the Greek smaragdos via the Old French esmeralde, and really just means 'green gemstone'. Innumerable fantastic stories have grown up around this magnificent gem. The Incas and Aztecs of South America, where the best emeralds are still found today, regarded the emerald as a holy gemstone. However, probably the oldest known finds were once made near the Red Sea in Egypt. Having said that, these gemstone mines, already exploited by Egyptian pharaohs between 3000 and 1500 B.C. and later referred to as 'Cleopatra's Mines', had already been exhausted by the time they were rediscovered in the early 19th century.

But it has also, for centuries, been the color of beauty and of constant love. In ancient Rome, green was the color of Venus, the goddess of beauty and love. And today, this color still occupies a special position in many cultures and religions. Green, for example, is the holy color of Islam. Many of the states of the Arab League have green in their flags as a symbol of the unity of their faith. Yet this color has a high status in the Catholic Church too, where green is regarded as the most natural and the most elemental of the liturgical colors.

American Topaz Diamond



American Topaz









The world's largest cut topaz, called the American Topaz, resides at the Smithsonian Institution in Washington, DC. A 172-faceted topaz weighing 22,892.50 carats (5785 kg), it's the largest cut yellow topaz in the world, and one of the largest faceted gems of any kind in the world. Originating from Minais Gerais, Brazil, it was cut over a period of two years. It was purchased by the Rockhound Hobbyists of America and presented to the Smithsonian Institution in 1988.

As stunning as this cut topaz is, another display at the Smithsonian is equally dazzling and awe-inspiring. That's a sherry-colored topaz "spray" from the Thomas Range in Utah. This color of topaz can be found in Mexico and Utah, but when it's exposed to sunlight, will become clear.

Other spectacular displays of natural crystals include a cluster of Stibnite, an ore of antimony, which has a bright metallic luster. This spectacular group of crystals is from Iyo, Japan and look like something from Superman's home!

Another huge mineral in the exhibit is the Smithsonite, named for James Smithson, who bequeathed the funds to establish the Smithsonian Institution. He first discovered this greenish zinc carbonate mineral from the Kelly Mine in New Mexico.

Some of the other don't miss items in the Smithsonian's Gem Collection are the Smithsonian Canary Diamond, a huge canary and diamond ring. The 98.6-carat Bismarck Sapphire is also part of the collection and is one of the world's largest sapphires. It originally came from Sri Lanka. It's also fascinating to see some of these gems in their raw uncut state, such as the large corundum crystal which is the mineral that sapphires are made of, and a very large beryl crystal, from which the emerald and aquamarine family of stones is derived

Portuguese Diamond



Portuguese Diamond







There's something so exciting about these incredibly large and perfect stones. Sometimes they have well-documented histories and we know where they came from and who owned them and when. But others have a past that's not as well-known, and that only adds to the romance and mystique surrounding them.

One such diamond is called the Portuguese Diamond. It is a 127-carat, cushion-cut diamond, shaped in an octagonal emerald shape. It's nearly flawless. While it's called the Portuguese Diamond, with a story that it was mined in Brazil and became part of the Portuguese Crown Jewels, there's really no true documentation that says definitively that that's where the diamond was mined. Must of the diamond's history is pure legend and conjecture. One can only imagine who wore this incredible stone!

One part of the diamond's history that is well-documented is that in February 1928 Peggy Hopkins Joyce traded a $350,000 pearl necklace for the diamond and $23,000 in cash. According to New York newspaper accounts, it was mounted on a diamond-studded platinum choker to be worn close around the throat (probably the same necklace described above). Miss Joyce performed in the Ziegfeld Follies, and had six husbands, at least five of whom were wealthy. She was said to be almost as fond of jewels as of men. Sometime prior to 1946 Miss Joyce placed the diamond on consignment to the group of jewelers mentioned above, in an unsuccessful attempt to sell it.

Harry Winston acquired the Portuguese Diamond from Miss Joyce in 1951, and for the next several years it traveled the country as part of his "Court of Jewels" exhibition. In 1957, Winston sold the diamond to an international industrialist, who then traded it back in 1962. In 1963, the Smithsonian acquired the Portuguese Diamond from Mr. Winston in exchange for 2,400 carats of small diamonds.

Marie Louis Diadem Diamond



Marie Louis Diadem




There were a few benefits to marrying the Emperor Napoleon, if you loved jewelry, that is! The Marie-Louise diadem, now part of the Smithsonian Collection, was a wedding gift from Napoleon I to his second wife, Empress Marie-Louise in 1810.

The diadem was originally part of a set that also included a necklace, comb, belt buckle, and earrings, all made of emeralds and diamonds set in silver and gold. They were all made by French Jeweler Etienne Nitot et Fils of Paris.

In the original diadem, there were 22 large and 57 small emeralds, along with 1002 brilliant-cut and 66 rose-cut diamonds. The central emerald weighed 12 carats. After the fall of the Emperor, Marie-Louise fled to Vienna and took her personal jewelry with her, including the diadem and other pieces that were made as part of a set, including a necklace, a pair of earrings and a comb.

Empress Marie-Louise left the diadem to her Hapsburg aunt, Archduchess Elise. Archduke Karl Stefan Hapsburg of Sweden, a descendent of the Archduchess sold the set to Van Cleef & Arpels in 1953. Between May 1954 and June 1956, the emeralds were removed and sold individually in pieces of jewelry as emeralds "from the historic Napoleon Tiara."

Between 1956 and 1962, Van Cleef & Arpels mounted turquoise cabochons into the diadem. In 1962, the diadem was displayed in the Louvre in Paris with the necklace, earrings, and comb in an exhibit about Empress Marie-Louise. In 1971, Marjorie Merriweather Post, heiress to the Post cereal fortune, purchased the diadem for the Smithsonian Institution.

There are 1,006 mine-cut diamonds weighing a total of 700 carats and 79 Persian turquoise stones weighing a total of 540 carats. In one respect, it's a shame that the original piece was dismantled to sell off the emeralds. Yet the diadem, reset with the turquoise cabochons is equally beautiful and made even more distinctive with the use of the less valuable turquoise.

Marie Antoinette Diamond Earrings



Marie Antoinette Earrings





There's no more fascinating subject in history than the doomed French Queen Marie Antoinette. Much maligned by history (she never said "Let them eat cake," in response to the people's need for bread), she was an unwilling part of the one of the greatest revolutions in history. And met an untimely end at the guillotine in 1793. While she loved jewelry, and possessed many magnificent jewels, she often preferred simple muslin gowns and very little jewelry. Many of the portraits of her by Elisabeth Vigee-Lebrun show her dressed just like that.

Two large, pear-shaped diamond earrings, weighing 14.25 and 20.34 carats respectively, are part of the Smithsonian Institution's collection. The diamonds once were supposedly set in earrings that belonged to Marie Antoinette and some sources say they were her favorite pieces of jewelry and she wore them constantly. They were taken from her during an attempt to flee France as the Revolution dawned and the position of the Royals became dangerous.

The diamonds were later acquired by the Grand Duchess Tatiana Yousupoff of Russia. When jeweler Pierre Cartier purchased the diamond earrings in 1928, their authenticity was attested to in an affidavit by Russian Princess Zenaide Yousupoff and her son, Prince Felix Yousupoff, stating that they originally belonged to Queen Marie-Antoinette and have never been reset in the one hundred years that they were in the family.

Marjorie Merriweather Post acquired the earrings from Pierre Cartier in October 1928. Harry Winston reset the large diamonds in platinum replicas of the original silver settings in 1959. Cartier, Inc. designed the triangular tops. In November 1964, Mrs. Post's daughter, Mrs. Eleanor Barzin, donated the earrings, along with the original setting to the Smithsonian Institution. The diamonds are originally from India or Brazil, the only significant sources of diamonds in the eighteenth century.

The Blue Heart Diamond



The Blue Heart Diamond






There is a spectacular diamond in the Smithsonian Collection called the Blue Heart Diamond. Fans of the movie Titanic might think the "Heart of the Ocean Diamond" was based on this stone, and it may have been! However, this diamond hasn't been cast in the ocean, but is safe and sound at the Smithsonian!
It has also been called the Eugenie Blue Diamond, although it's uncertain that the Empress Eugenie ever owned this particular stone. It was cut in Paris between 1909 and 1910, but the stone's origin - Africa or India - is unclear.
It is an enormous heart-shaped, blue diamond weighing 30.82 carats. Its current setting is in a platinum ring, surrounded by white diamonds. It changed hands among famous jewelers - such as Cartier and Van Cleef & Arpels - and owners until it was bought by Harry Winston in 1959 who mounted the diamond in its current ring setting. Winston sold the ring to Marjorie Merriweather Post. Mrs. Post donated the ring to the Smithsonian and it remains there with other famous blue diamonds, including the Hope Diamond and the Heart of Eternity Diamond.
These famous blue diamonds have recently gone through a grading and examination process, to classify their colors and to determine the source of the color. The Hope Diamond is classified as Fancy Deep Grayish-Blue. The Heart of Eternity has been classified as a Fancy Vivid Blue. The Blue Heart Diamond has not yet been classified, but some experts categorize it as either Fancy Vivid Blue or Fancy Deep Blue.
Blue diamonds are of particular interest to scientists not only because of the color and the impurities that create it, but because blue diamonds also have an electric conductive property that makes them unique among clear and other colored diamonds.

Napoleon Diamond Necklace



Napoleon Diamond Necklace




One of the most spectacular all-diamond pieces of jewelry in the Smithsonian Insitution is the Napoleon necklace. Thought to have originally been owned by Catherine the Great of Russia, it was presented by the Emperor Napoleon of France to his second wife, Marie-Louise of Austria on the birth of their son in 1811.
The silver and gold set necklace contains172 diamonds weighing 275 carats - 28 oval and cushion-cut diamonds, dangling 19 briolette-cut oval and pear shaped diamonds and accented by small, round diamonds and diamond set motifs in a silver and gold setting.
The diamonds are cut in "old mine" style, the precursor to the modern brilliant cut, and have a high degree of fire (flashes of color as the stone moves in light), but less brilliance due to less light refraction through the top of the stone.
The necklace has an estimated total gem weight of 275 carats, and the largest single diamond on it weighs approximately 10 carats. When Marie-Louise died in 1847, the necklace was given to her sister-in-law, Archduchess Sophie of Austria, who removed two stones to shorten the necklace. Earrings were made with the two removed stones, the whereabouts of which are unknown.
In 1872, the necklace was bequeathed to the Archduchess' son, Archduke Karl Ludwig of Austria. In 1948, Archduke Ludwig's grandson, Prince Franz Joseph of Liechtenstein, sold the necklace to a French collector who then sold it to Harry Winston in 1960. Marjorie Merriweather Post obtained the necklace from Winston and donated it to the Smithsonian Institution in 1962.
It's difficult to value a piece like this in today's market. However, in 1993, the auction house Christie's in Geneva sold another necklace that Napoleon had given to Marie-Louise that was composed of rubies and diamonds. This necklace sold for $13 million.

Victoria Transvaal Diamond



Victoria Transvaal Diamond





The Victoria-Transvaal is a 67.89-carat, brownish-yellow pear shaped stone. It was cut from a 240-carat crystal that was found in the Transvaal, South Africa.
The first cutting produced a 75-carat 116-facet stone that measured 1 x 1³/8 inches; a recutting retained the same length and width, but reduced the depth to better proportions, making it more brilliant.
The diamond has been featured in several Hollywood films, including a Tarzan episode from 1952 titled Tarzan's Savage Fury, and in leading exhibitions in the United States and Canada.
The necklace was designed by Baumgold Brothers, Inc, and consists of a yellow gold chain with 66 round brilliant-cut diamonds, fringed with ten drop motifs, each set with two marquise-cut diamonds, a pear-shaped diamond, and a small round brilliant-cut diamond (the total weight of the 106 diamonds is about 45 carats). The configuration of these stones makes them look like small angels! The necklace was donated by Leonard and Victoria Wilkinson in 1977 to the Smithsonian Institute, Washington D.C.
Other colored diamonds in the Smithsonian Collection include the 8.30-carat Shepard Diamond. This stone is from South Africa, and was acquired by the Smithsonian Museum in exchange for a collection of small diamonds that had been seized as smuggled goods by the United States Customs Service. The diamond is named for the Smithsonian employee who helped facilitate the transaction.
An extremely rare red diamond resides at the Smithsonian as well. This is the De Young Red, a 5.03-carat, brilliant cut red diamond. The main kite-shaped facets on the crown are divided in two, giving the stone more brilliance than a standard round brilliant cut. The stone is not pure red but has a slight brown hue, which makes it appear like a fine red garnet and indeed, it was once purchased as such at an estate sale. It is the third largest red diamond in the world, after the Moussaieff Red (5.11 carats) and the Red Diamond (5.05 carats).

The Blue Hope Diamond



The Blue Hope: 45.52 carats






A dark, steely blue stone from India, the diamond eventually named the Hope Diamond is more notorious than any other diamond. It was originally purchased by a French merchant traveler, who sold it to King Louis XIV in 1668. Set in gold and suspended on a neck ribbon, the king wore the "Blue Diamond of the Crown" or "French Blue" on ceremonial occasions. During the French Revolution in 1792, when Louis XVI and Marie Antoinette attempted to flee France, the French Blue was stolen.
Evidence suggests that it was acquired in the early 1800s by King George IV of England, and likely sold at his death in 1830 to help pay off his debts. The diamond was subsequently purchased by Henry Philip Hope, from whom it takes its name. While in the possession of the Hope family, the diamond acquired its grim reputation for bad luck: The entire Hope family died in poverty.
Henry Thomas Hope's possession of the diamond was uneventful. However, one of his heirs who came to own it, Lord Francis Hope, was in financial difficulties due to a penchant for gambling. After numerous attempts (and despite the opposition of other family members) he finally succeeded in selling the Hope diamond in 1901. The diamond was purchased by a New York diamond merchant, Simon Frankel. At this point, the diamond was said to be involved in several bizarre events, although none have been substantiated.
First, a French broker by the name of Jacques Colot was said to have bought the stone before becoming insane and committing suicide. Next, a Russian or Eastern European prince, Ivan Kanitowsky, supposedly loaned or gave the diamond to an actress at the Folies Bergère, who was shot the first time she wore it. The prince himself was stabbed to death by revolutionaries; a Greek jeweler who sold the diamond to the Sultan of Turkey was thrown over a cliff while riding in a car with his wife and child. Again, it is difficult to separate the fact and fiction.
It is known that after several owners, the Hope diamond was sold by Cartier's to Mrs. Evalyn Walsh McLean of Washington, D.C. Some researchers believe it was Pierre Cartier who popularized the story that the stone brought misfortune to its owners - and anyone who touched it.
Mrs. McLean was the daughter of Thomas F. Walsh, who amassed a fortune in gold mining. She spent her early childhood in mining camps in Colorado and South Dakota, but was later educated in Washington D.C. and in Europe. She married Edward Beale McLean, son of the owner of the Cincinnati Enquirer and the Washington Post.
Although Mrs. McLean refused to believe in the legendary Hope "curse" she also endured a number of family tragedies. Her brother died young; her nine-year-old son was run over by a car and killed; her ex-husband drank heavily and died in a mental institution; and her only daughter died of a drug overdose at age 25. Mrs. McLean never recovered from the latter tragedy, and passed away only a year later. Upon her death, Mrs. McLean's extensive jewelry collection was purchased by Harry Winston Inc. of New York City. After exhibiting it among other notable gems for the next 10 years, the firm donated it to the Smithsonian Institution, where it remains one of its premier attractions.

The Regent Diamond



The Regent: 140.50 carats






This great stone, originally a diamond rough of 410 carats, was said to be discovered in 1701 by an Indian slave near Golconda. Golconda was a mountain fortress and a center for trading in India that included a diamond storehouse. The diamond was first owned by William Pitt, the Prime Minister of England, but the circumstances surrounding his acquisition of the gem have been called into question several times. Pitt arranged for the stone to be cut into its current cushion-shaped brilliant by the only person in England considered capable of the task, which took two years. The result was a stunning gem that is considered the most perfectly cut of all the celebrated diamonds of old.
The Regent is characteristic of the finest Indian diamonds, and has a beautiful light blue tinge. Known at the time as the Pitt, the diamond was sold to the Duke of Orleans, Regent of France, who was at first hesitant to purchase the gem because of the perilous state of the Treasury. Ultimately, the Duke of Orleans relented, and shortly thereafter, the stone was renamed "The Regent." Later, it was set in the coronation crown of King Louis XV, and later in a headband worn by his Queen. Many of the French Crown Jewels were reset numerous times at the behest of the queen. Sadly, in September 1792, the Regent and other great diamonds in the Crown Jewel collection were stolen, some disappearing forever. Fortunately, the Regent reappeared in a Paris attic a year later. After coming to power in 1799, Napoleon Bonaparte ordered the diamond set in his sword hilt, which he carried at his coronation two years later. Today, the Regent can be admired at the Louvre in Paris.

The Centenary Diamond



The Centenary: 273.85 carats




The 100-year anniversary of De Beers Consolidated Mines coincided with the fortuitous discovery of an extraordinary diamond rough. At its centennial banquet, the De Beers chairman announced the recovery of "a diamond of 599 carats which is perfect in color - indeed, it is one of the largest top color diamonds ever found. Naturally, it will be called the 'Centenary Diamond.'"
The Centenary diamond was found at South Africa's Premier Mine on July 17, 1986 using an electronic x-ray recovery system. In its rough form, the stone resembled an irregular matchbox, with angular planes, a prominent, elongated protrusion at one corner, and a deep concave on the largest flat surface. Clearly, it would be daunting to cut, with no obvious approach readily apparent.
It took a master cutter three years to transform the stone into the largest modern-cut flawless diamond. The Centenary has 75 facets on top, 89 on the bottom and 83 on the girdle, for a total of 247. The amazing result was achieved using a combination of some of the oldest cutting methods and the most sophisticated technology. Today, this marvelous gem, exemplifying the ultimate in fire and brilliance for which the diamond is prized, is part of the British Crown Jewels. It was presented at the Tower of London in 1991, where it is on permanent display.

The Orlov Diamond






The Orlov: 300 carats (original rough)









The history of this famous diamond is characterized by legend, fact, speculation and theory. But it is considered one of the most important items in the Treasures of the USSR Diamond Fund, one of the world's greatest collections of gems and jewelry. The USSR Diamond Fund comprises many of the historical jewels that were amassed by the rulers of Russia before the Revolution of 1917, along with exceptional diamonds unearthed in the former Soviet Union during the last three decades.
The Orlov's shape has been likened to half of a pigeon's egg. It has roughly 180 facets and is mounted in the Imperial Scepter, fashioned during the reign of Catherine the Great. The Orlov has been confused with the Great Mogul, a fascinating Indian gem that apparently disappeared without a trace. Another account holds that the earliest known fact about the Orlov is that it was set as one of the eyes of an idol in a sacred temple located in the South of India. Another tale suggests that it was set as the eye of God in the temple of Sri Rangen, and was stolen by a French soldier disguised as a Hindu.
The stone takes its name from Count Grigori Grigorievich Orlov, a Russian nobleman and army officer who caught the fancy of the Grand Duchess, destined to become Catherine the Great. Catherine ascended to the throne after her husband was dethroned and murdered in a coup carried out with the help of Orlov. After she purchased the stone, it was set beneath the golden eagle. Another legend suggests that upon entering Moscow, Napoleon sought the gem, which was concealed in the tomb of a priest in the Kremlin. Reportedly, when one of Napoleon's lieutenants attempted to secure the Orlov, the invaders were cursed by the ghost of the priest, and Napoleon and his bodyguards fled empty-handed.

The Taylor-Burton



The Taylor-Burton: 69.42 carats




As many people today remember, this was the spectacular pear-shaped diamond the late actor Richard Burton bought as a gift for his fifth wife, Elizabeth Taylor. The stone came from a rough piece of 240.80 carats that was purchased by Harry Winston. Once it was cut, the larger piece yielding the pear-shaped stone was sold to Mrs. Harriet Annenberg Ames, whose brother, Walter Annenberg, was the American ambassador in London during Richard Nixon's presidency. Mrs. Ames felt uncomfortable wearing such a large diamond, and sent it to auction in New York in October, 1969.
The diamond was purchased at auction for a then-record $1,050,000, with the understanding that it could be named by the buyer. Cartier of New York proved the successful bidder and immediately christened it "Cartier." However, the next day, Richard Burton bought the stone for Elizabeth Taylor for an undisclosed sum. She first wore the gem as a pendant at Princess Grace's 40th birthday party in Monaco.
In 1978, following her divorce from Mr. Burton, Miss Taylor announced that she was putting the diamond up for sale, with the proceeds dedicated to building a hospital in Botswana. Due to the tremendous costs of showing it, prospective buyers were required to pay $2,500 just to inspect the diamond. Miss Taylor eventually sold the Taylor-Burton for a reported figure of $5 million in 1979. The gem was last seen in Saudi Arabia.

The Sancy Diamond



The Sancy: 55 carats






This pear-shaped stone with a confused heritage disappeared during the French Revolution in 1782. It was originally owned by Charles the Bold, Duke of Burgundy, who lost the diamond in battle in 1477. It was named after a later owner, Seigneur de Sancy, a French Ambassador to Switzerland during the late 16th century. There are numerous questions regarding how Mr. Sancy obtained his diamond, but most likely, he acquired it on his travels in the Far East.
Nicholas de Sancy served two French monarchs loyally: He loaned the diamond to the French king, Henry III, who strategically placed it on his cap to conceal his baldness. It was also pledged by Sancy for the purpose of raising troops in Switzerland. He employed his diamond again on behalf of his sovereign, now Henry IV, the first of the Bourbon dynasty. By 1596, Sancy himself was in need of money and eventually sold the large diamond to King James I of England. In 1625, Charles I disposed of other diamonds but retained the Sancy, which was taken by Queen Henrietta Maria along with other jewels in the Royal Treasury. It later came into the possession of Cardinal Jules Mazirin, acting First Minister of the Crown, who bequeathed the Sancy and another stone to the French Crown. Following the French Revolution, a stone believed to be the Sancy found its way to a Spanish nobleman, and eventually in 1828 to Prince Nicholas Demidoff, whose family owned industries and silver mines in Russia. The Sancy passed to his son, who gave it to his Finnish bride.
Following additional travels around the world, the Sancy was purchased by William Waldorf Astor in the 1890s for his wife, Lady Astor. Lady Astor, the first woman to sit as a Member of Parliament in the House of Commons, wore the Sancy set in a tiara at numerous state occasions. In 1978, the four Viscount Astor sold the Sancy, reputedly for $1,000,000. It is now on view at the Louvre in Paris.

The Dresden Green Diamond



The Dresden Green: 41 carats




This almond-shaped stone is the largest apple-green diamond known. Its green color is attributed to the crystal’s close contact with a radioactive source at some point in its lifetime. The Dresden Green, which probably originated in a rough crystal of 100 carats or more, is unique among world-famous gems for not only its color, but also its elongated shape. The Dresden Green gets its name from the capital of Saxony where it has been on display for more than 200 years.
Although of Indian origin, nothing was known of the diamond until Frederick Augustus II of Saxony purchased it at the Leipzig Fair in 1743 for about $150,000. Set in an elaborate shoulder knot, the stone was exhibited with the other Crown Jewels of Saxony in the famous Green Vaults under the Dresden Palace. After World War II, these gems were confiscated by the Russians, but they were returned to Dresden in 1958, and are again on display in the palace.

The Jubilee Diamond



The Jubilee: 245.33 carats




The Jubilee is a magnificent, colorless cushion-cut diamond that at one time ranked the sixth largest diamond in the world. More importantly, many gemologists consider the Jubilee the most perfectly cut of all large diamonds. That is because its facets are so exact that the gem can be balanced on the culet point, which measures less than 2 millimeters across.
The original rough stone weighed 650.80 carats and was an irregular octahedron in shape, lacking definite faces. It was found in late 1895 at the Jagersfontein Mine in South Africa, and acquired by a syndicate of London diamond merchants who sent it to Amsterdam for polishing. The first cleaving of the rough yielded a fine pear-shaped diamond in excess of 13 carats that was presented by the king of Portugal to his wife. The remaining large piece was polished into the stone known as the Jubilee.
During the cutting period, when the stone's exceptional size and purity became evident, there were initial plans to present the diamond to Queen Victoria upon completion, but this did not occur. However, the following year, 1897, marked the Diamond Jubilee of Queen Victoria. Therefore, the gem was appropriately renamed the Jubilee to commemorate the occasion. Its introduction was also significant in the world of diamonds, which saw its first diamond with the characteristics of both the rose and brilliant cuts - which would subsequently be known as the Jubilee cut.
In 1900 the syndicate displayed the Jubilee at the Paris Exhibition, where it was an immensely popular attraction. Shortly thereafter, it was purchased by an Indian industrialist and philanthropist, Sir Dorabji Jamsetji Tata, whose family was instrumental in modern India's economic development. Tata's heirs sent the Jubilee to Cartier for sale. Cartier exhibited it with other historic diamonds prior to selling it to a Paris industrialist and arts patron, M. Paul-Louis Weiller, who remains its present owner.

The Cullinan Diamonds



The Cullinan Diamonds: 3,106 carats (rough)




The largest gem-quality diamond ever found was discovered on January 26, 1905 in the Premier Mine in South Africa. The original rough of the Cullinan Diamod measured 3,106 carats and weighed about 1 1/3 pounds. It was notable for its exquisite color and exceptional purity. Just as interesting, the stone possessed a surprisingly smooth cleavage face on one side, leading many experts to believe that the huge stone was only a piece of a larger diamond that was broken up in the weathering process. The diamond was named for Sir Thomas Cullinan, who opened the Premier Mine. The Transvaal Government bought the diamond rough for $750,000 and presented it to England's King Edward VII on his birthday in 1907. The next year, King Edward sent the stone to the renowned Asscher's Diamond Co. in Amsterdam for cutting. Following months of exacting study, the rough stone was cleaved into nine major gems, with the largest two retained by the Royal Family for the Crown Jewels. The rough also yielded 96 smaller brilliant-cut stones and 9 1/2 carats of unpolished pieces.
The two largest stones are known as the Cullinan I and Cullinan II:
The Cullinan I (also known as the Great Star of Africa): 530.20 carats
The Cullinan I is a magnificent pear-shaped diamond with 74 facets. It is the largest stone cut from the Cullinan rough and, until recently, the largest cut diamond in the world. (That record is now held by the Unnamed Brown, a golden brown cushion shape diamond weighing 545.67 carats.) King Edward called it "The Great Star of Africa" and ordered it to be set in the British Imperial Scepter, which had to be redesigned to accommodate it. The Scepter is on permanent display in the Tower of London.
The Cullinan II (also known as the Lesser Star of Africa): 317.40 carats
A cushion-cut brilliant, the Cullinan II is the fourth-largest cut diamond in the world. Nicknamed the Lesser Star of Africa, it is also part of the British Crown Jewels. This square stone is set in the British Imperial State Crown, on display in the Tower of London.

The Koh-I-Noor Diamond (Mountain of Light)







The Koh-I-Noor (Mountain of Light) Current Weight: 105.60 carats Original Weight: 186 carats








It was first reported in 1304 as a diamond owned by the Rajah of Malwa. Following wars in the 1500s, it ultimately fell into the hands of the Sultan Babur, and for the next 200 years the 186-carat diamond was one of the precious jewels of the Mogul Emperors. It was believed to have once been set as one of the peacock's eyes in the famous peacock throne of Shah Jehan, who reigned in the early 1650s. In 1739, Nadir Shah, who built Persia into a major power, invaded Delhi. He obtained the Koh-I-Noor - along with the sumptuous Peacock Throne - from the vanquished Indian Emperor Mohammed Shah. Allegedly, when his pillage of Delhi failed to uncover the huge stone, he was told by one of the harem women that the conquered Mogul emperor had hidden it inside his turban. Taking advantage of an Oriental custom, Nadir Shah invited his captive to a feast and suggested they exchange turbans. Following the feast, he unrolled the turban and released the great gem. Seeing it, Nadir Shah cried, "Koh-I-Noor," which means mountain of light.
Nadir Shah took the gem back to Persia, and following his assassination in 1747, the diamond was fought over by his successors. When the state of Punjab was annexed to British India in 1849, the East India Company took it as insurance for the Sikh Wars. As part of its 250th Anniversary festivities, the East India Company presented the Koh-I-Noor to Queen Victoria in 1850.
The stone was displayed at the famous Crystal Palace Exposition, but visitors were disappointed that the diamond did not show more fire. So Victoria had the stone recut, reducing the diamond to its present size. In 1911, a new crown was made for the coronation of Queen Mary featuring the Koh-I-Noor as the center stone. In 1937, it was transferred to the crown of Queen Elizabeth (now Queen Mother) for her coronation. Currently, it is on display in the Tower of London with the British Crown Jewels.

Cushion Cut Classic Series



Cushion Cut Classic Series



Starting at $25
The Cushion cut was one of the most popular diamond cuts ever. For more than 70 years from 1830 to till the dawn of the 20th century, this was how the majority diamonds were cut. Sometimes referred to as a pillow cut, the Cushion cut has an open culet (the bottom of the gemstone) and a rectangular to square shape, with rounded corners and a facet plan to give the diamond depth. The Cushion cut was originally cut for candle light. This is quite different from todays gemstones, which are cut for brighter denser electric light. The beauty of a Cushion cut is the depth of the jewel. The facets allow the eye to travel into the gem. The Cushion cut is a calm soothing cut. At a romantic candlelight dinner, the Cushion cut is at its best.

Trillion Cut Classic Series



Trillion Cut Classic Series





Starting at $20
The trillion cut is a dazzling and versatile gemstone shape. One of the more unusual cuts, the trillion displays a very sharp brilliance or fire when the gemstone is cut to the correct depth allowing good scintillation. Trillions are triangular in shape, usually with truncated corners, with a variety of facets. They can be used in earrings, solitaires, wedding bands, necklaces, bracelets, and pendants. Actually, the trillion can replace the standard shape anywhere, adding its unique style, fire and brilliance to create excitement. Trillion is a more modern cut based upon a brilliant style cut. The fire and beauty of this cut is spectacular. The trillion cut has a large well-proportioned surface area. This feature results in a big look as compared to the body weight of the other cuts. A one-carat trillion jewel looks as large as a one-and-a-half carat round gemstone. A trillion cut is an equilateral triangle with 50 facets.

Round Brilliant Cut Classic Series



Round Brilliant Cut Classic Series





Starting at $20
The term brilliant-cut was coined at the end of the 17th century and was represented by several forms of faceted gemstones. During the early 18th century, Brazil gave rise to the cushion-shaped old-mine cut, a forerunner of the modern brilliant cut. Back at the turn of the century, marcel tolkowsky, a member of a large and powerful gemstone family, calculated the cuts necessary to create the ideal shape. As part of his phd thesis in mathematics, tolkowsky considered variables such as index of refraction and covalent bond angles to describe what has become known as the brilliant cut. This work, diamond design: a study of the reflection and refraction of light in diamond, described the best proportions of a round brilliant cut, which would provide a balanced return of light (brilliance) and dispersion. There are 58 facets in a round brilliant cut.

Triangle Cut Signature Series



Triangle Cut Signature Series






Starting at $77
The Triangle cut, enchanting in its own right, is often confused with the Trillion cut. The Triangle cut is a stepped facet cut, while the Trillion cut is based upon a brilliant style cut. Step cut gems have concentric rows of facets running parallel to the girdle. The Triangle cut, first designed in Amsterdam, is cut into the shape of a wedge. The corners of the Diamond Nexus Labs Triangle cut are pointed, as opposed to the Trillion cut with truncated corners. The step cut has rows of facets that resemble the steps of a staircase. The Emerald cut and Baguette cut are also examples of step cuts. The Triangle cut is used in a variety of heart-stirring jewelry, but most often commands center stage in ladies rings.

Radiant Cut Signature Series



Radiant Cut Signature Series





Starting at $90
The Radiant cut is a beautiful combination of the classic elegance of the Emerald cut and the sparkle of the Round Brilliant. The Radiant cut is similar to the Princess cut but projects a more rectangular outline and has blocked corners like those of an Emerald cut. The cutting is a combination of the step-cutting of the Emerald cut diamond with some triangular faceting of the Round Brilliant cut. The Radiant cut is dramatic as a solitaire but also looks great paired with side staging stones such as Baguettes, Trillions, or Princess shapes. A Radiant cut gemstone should be set with special prongs to hold the blocked corners securely.

Oval Cut Signature Series



Oval Cut Signature Series




Starting at $91
The Oval-shaped brilliant is very similar to a Round except it is elliptical. It was invented by Lazare Kaplan in the early 1960s. Shape appeal is very important with Oval brilliants. The Oval cut is an elliptical shape when viewed from the top. The Oval cut to a ratio of the length to the width should be about 1.5:1. If it is much greater, you will see a dark area. This is commonly called a bow tie effect. If the ratio is much less then 1.5:1, the gemstone looks like a misshapen Round. A well cut Oval gemstone can be nearly as bright as a well-cut Round brilliant shape, the angles are closer to ideal for the maximum optical effect that well cut diamonds can produce. Ovals provide a bigger surface area than a round with the same carat weight and therefore are an excellent option for those looking for the brilliance of the round but a bigger size. The Oval brilliant cut has 58 facets. Diamond Nexus Labs Signature Series Gemstones are the only Man-Made Diamond Simulant Gemstones to be Certified and Graded by a Major Diamond Grading Agency.

Marquise Cut Signature Series



Marquise Cut Signature Series





Starting at $106
Legend says that the name of this cut came when King Louis XV commissioned his jeweler to make a gemstone in the shape of his mistress lips: the Marquise Madame de Pompadour. Light passes through the back of the gemstone due to the criticality of the angles needed to reflect the gemstone being too steep. The crown cut is sometimes modified in the Marquise to form what is called a French Tip, where the bezel facet at the point of the gemstone is eliminated. Diamond Nexus Labs stays in the sixty percent range for this lovely cut, and to avoid extremely thin girdles. The ideal ratio of length to width should be about twice the length as the gemstone is wide (2:1 aspect ratio). The Marquise brilliant contains 58 facets. Diamond Nexus Labs Signature Series Gemstones are the only Man-Made Diamond Simulant Gemstones to be Certified and Graded by a Major Diamond Grading Agency. All Signature Series Gemstones are Laser Inscribed with Detailed Information that certifies the Authenticity and Exclusivity of the Gemstone and Insures your Peace of Mind.

Heart Cut Signature Series



Heart Cut Signature Series





Starting at $89
The Heart is the ultimate symbol of love. And since most Heart-shaped gemstones are nearly round, each has the advantage of having a nearly round pavilion that provides its beautiful brilliance. The Heart-cut brilliant bears some similarity to the Pear shape, except that there is a cleft at the top. The shape appeal is especially important with hearts. Diamond Nexus Labs makes certain that there is always a perfectly symmetrical appearance where the lobes (top arches) are of even height and breadth, and the overall shape exceptionally pleasing to the eye. The Heart shape is one of those special cuts that follow more human and emotional values. The technical benefit is that a Heart cut gemstone has a roundish pavilion, and when proportioned, it can drive the sparkle and scintillation back out of the jewel. Optimum shape is: length to width ratio 0.9-1.2:1, which is most gratifying to the eye. Diamond Nexus Labs Signature Series Gemstones are the only Man-Made Diamond Simulant Gemstones to be Certified and Graded by a Major Diamond Grading Agency.

Emerald Cut Signature Series

























Emerald Cut Signature Series





Starting at $96
The Emerald cut is rectangular with cut corners. It is a step cut as opposed to a brilliant cut. Step cuts are comprised of larger facets which act like mirrors. The facets are broad with flat planes resembling the steps of a stair. Thats why it is referred to as a step cut. Unlike the Marquise brilliant, there is no bow-tie effect on an Emerald cut. The Emerald cut looks like a rectangle from the top, with truncated corners. These are beautiful gemstones with stepped facets; the sheen tends to be large flashes of these stepped angles on the pavilion of the gemstone. Because of the angle, size and shape of the facets, the Emerald cut shows less brilliance and fire (dispersion) than the other brilliant cut diamonds. However, the Emerald cut gemstone reveals a classic beauty and elegance not seen in other cuts. The length-to-width ratios are 1.5:1 to 1.75:1. Diamond Nexus Labs Signature Series Gemstones are the only Man-Made Diamond Simulant Gemstones to be Certified and Graded by a Major Diamond Grading Agency. All Signature Series Gemstones are Laser Inscribed with Detailed Information that certifies the Authenticity and Exclusivity of the Gemstone and Insures your Peace of Mind.
