Diamonds

Black Diamonds
Natural black diamonds are essentially colored by dark inclusions or impurities, which are great in number and evenly distributed throughout the stones. Many black diamonds in the marketplace are treated for even coloration and durability.

Large natural black diamonds are very rare, but irradiated black diamonds are abundant and utilized in many jewelry styles.

To a lot of rap music artists the latest must-have symbol of conspicuous consumption is jewelry made up of black diamonds.
Black diamonds are called Fancy Black with a notation of natural or treated color on laboratory reports.

GIA does not grade black diamonds as they fall outside of its normal clarity range, but the lab will issue a "Colored Diamond Identification and Origin Report (CDIOR) for identification purposes.
Known as the Black Orlov, or “The Eye of Brahma,” the most famous black diamond is haunted by a curse that reportedly began when the original 195-carat diamond was removed from the eye (forehead) of the idol of Brahma at a shrine near Pondicherry, India.

The diamond is tied to the deaths of three former owners who apparently killed themselves. In an attempt to break the curse, the diamond was re-cut into three separate gems and since has been owned by a succession of private owners, all of whom seem to have escaped the curse. J. Dennis Petimezas, current owner of the famed diamond has found no reported tragedies linked to the diamond since 1947.
The Spirit of de Grisogono at 312.24 carats is the world's largest cut black diamond, and the world's 5th largest diamond. In a white gold mounting, it is set with 702 white diamonds totalling 36.69 carats.

The man behind the stone is famous Swiss jeweler de Grisogono. He was the first major jeweler to create eye-catching collections of black diamond jewelry and watches. He is also responsible for cutting the Gruosi Diamond, the largest heart-shaped black diamond in the world.

Type IIb diamonds, which account for 0.1% of gem diamonds, are usually light blue due to scattered boron within the crystal; these diamonds are also semiconductors. A blue-grey color may also occur in Type Ia diamonds and be unrelated to boron. While extraordinarily rare, blue diamonds are not the rarest.

They are more uncommon than yellow diamonds, which have nitrogen in them, but they lose out in rarity to green, black, pink, orange, purple, and red.


The 10.10-carat De Beers Millennium Jewel 4 sold for $32 million in April of 2016.
The Hope Diamond is 45.52 carats and is the largest deep-blue diamond known. The stone can be traced to Golconda and is considered by many to be the most famous diamond in the world.

Chameleon Diamonds
The rarity of chameleon diamonds is due to their unusual ability to change color temporarily when heated to about 150°C, or after prolonged storage in the dark.

Chameleon diamonds will show different colors if observed under halogen light, incandescent light and daylight. If Chameleon diamonds are exposed to heat they can change to a greenish-yellowish color very quickly and when they cool down and stabilize their normal color will return; this is known as thermochroism.
With all natural fancy color diamonds, an element other than carbon has made its way into the diamond which results in a new color.
In the case of Chameleon diamonds, an excess of hydrogen and a small amount of nitrogen has entered the diamond and this creates the unique colour-changing property. Most Chameleon Diamonds return to a green shade after exposure to heat or light. These diamonds usually fluoresce yellow. They often take on a strong red glow when they are being polished.
The Chopard Chameleon Diamond is a 31.32 carat oval-cut chameleon diamond and the largest known.

Champagne Diamonds
Beauty is a powerful thing - almost as powerful as semantics. There's no better evidence for this than the surging popularity of champagne diamonds - colored diamonds that in actuality, are brown diamonds with a luxe name and a yellowish shade.

As alluring and sought after as champagne diamonds are today, they weren't always so appreciated.
In the past, natural fancy brown diamonds weren't especially trendy. However, champagne diamonds have managed to gain increasing attention in recent years from collectors and investors.

When Rio Tinto's Argyle Mine determined that nearly half of the stones in their deposit were brown, it was clear that new marketing tactics were required. They coined the term "champagne diamonds," which suggested an air of luxury, elegance and affluence.
The word "champagne" is not used on grading reports from the GIA. Instead, the color would be described as fancy light yellow brown, fancy yellowish brown, or similar.
The Argyle Mine has devised a different color scale specifically to grade champagne diamonds, which ranges from C1 to C7. C1 to C2 are a light champagne, C3 to C4 are medium champagne, C5 to C6 are dark champagne, and C7 is considered "cognac.'
A major reason that champagne diamonds have been gaining vogue is that they have been embraced by the most fashion-forward A-list celebrities.

As with all colored diamonds, the color and its strength of hue is the most significant factor in determining value. The darker and rare cognac diamonds come at the highest cost, while champagne diamonds on the lighter end of the spectrum (C1 to C3) are more common and therefore less expensive.
The most well-known champagne diamond is the Golden Jubilee. It weighed 755 carats rough and resulted in a 545.67 carat gemstone. It's the largest faceted diamond in the world. Discovered in South Africa's Cullinan Diamond Mine in 1985, it was given to the King of Thailand in 1997 to celebrate his reign.

The Great Chrysanthemum Diamond is a fancy brown pear shaped modified brilliant cut that measures 104.15 carats. The diamond originated in South Africa.

Gray Diamonds
A combination of black and white, gray is a non-spectral color. In their purest forms, gray color diamonds come quite close to colorless stones.

Among colored diamonds, gray diamonds are relatively unknown. This may be due to their extreme rarity. Far more rare than yellow and brown diamonds, gray diamonds are in the lower range of fancy colored diamonds prices ... their pricing is so attractive that they can be considered an alternative to white colorless diamonds based on price.
Most gray colored diamonds get their color due to a high concentration of hydrogen, and rarely boron like blue diamonds.
In the niche of gray diamonds, there are nearly endless options. The human eye can distinguish up to 500 shades of gray and this is probably the number of gray diamond colors there are.

Gray diamonds are graded in the following intensity levels: Light Gray, Fancy Light Gray, Fancy Gray, Fancy Dark Gray, and Fancy Deep Gray.


The most common color modifiers according to the GIA are yellowish, greenish, bluish and violet.


Fancy Dark Violet Gray Diamond

There are few notable gray diamonds because they barely exist. However, two of the most famous diamonds in the world are blue diamonds with a gray modifier (gray blue diamonds): the Hope Diamond and the Wittelsbach Diamond (until Graff re-polished it to a pure blue).

The most famous gray colored diamond is the Sultan of Morocco. The diamond has a cushion cut, a blue hue and weighs 35.27 carats.

Green Diamonds

The 5.03 carat Fancy Vivid Green 'Aurora Green' made $ 16.8m or $3.3m per carat in 2016.
Green diamonds are among the rarest of all fancy colors. The green color is caused by exposure to radiation or radioactivity and is extremely unique.

Natural radiation creates an external skin or surface of green color. It is uncommon for the green color to reach deep within a diamond.
Lab graders assess the natural color of green diamonds by this skin. Irradiated green diamonds are often found in the marketplace, so determining natural color for value is key. Labs may be unable to conclusively determine the natural origin of green diamonds because the cause is radiation.

1.56 carat, Fancy Vivid Green Diamond
Green is the color between blue and yellow, so common secondary colors in green diamonds include bluish green and yellowish green, and if the color is desaturated, grayish green or brownish green. Natural green diamonds are second to red diamonds as the world's rarest fancy color. True greens devoid of secondary hue are the most valuable among natural green diamonds.

The green diamond has a very strong emotional correspondence with safety as it is the most restful color for the human eye. Green suggests both stability and endurance. Aqua green is associated with emotional healing and protection while Olive green is the traditional color of peace.
The Dresden Green is a 40.70 carat, pear shaped stone with a VS1 clarity grade. It was reported as one of the largest and finest natural green diamonds ever discovered.
The Ocean Dream The diamond is a 5.51-carat, fancy deep blue-green, shield-shaped diamond.

It is the only natural diamond known with this color combination.
The Chopard Chameleon, is a 31.31ct Oval-cut diamond which appears green in bright light but looks yellow in darkness. This stone was one of the first reported by the GIA as a chameleon in the late 1950s.

Orange Diamonds
The largest fancy-vivid orange diamond known to exist sold for 32.6 million Swiss francs ($36 million) at Christie’s International in Geneva in late 2013.

The 14.82-carat pear-shaped stone’s price was about $2.4 million per carat, this was a per-carat record for any colored diamond at a public sale. The gem also set a record for an orange diamond of its type.

A 4.08-Carat Fancy Vivid Orange Diamond Ring blew past it's US$1.6 – 1.8 million estimate at Sotheby's Hong Kong auction in April 2016, bringing $ 2.3m

The 'Mandarin Orange' is a 4.19-Carat Fancy Vivid Orange Diamond. It sold for $2.9 million in 2011.

Orange Diamonds may contain a brown, yellow or pinkish modifying color.
The majority of diamonds contain some nitrogen. In orange diamonds the nitrogen atoms have grouped themselves in a very specific way. This happens during and right after the diamond is formed. Nitrogen arrangements absorb light in the blue and yellow region of the spectrum producing an orange color.
The strength of colour is one of the most important factors in determining the value of a natural color diamond. The value increases exponentially with the intensity of the most prominent colour within the diamond. Pure Orange diamonds are impossibly rare.
The Pumpkin Diamond is 5.54 carats and rated as Fancy Vivid Orange by the GIA. Halle Berry wore the ring to the 2002 Oscars where she won the Academy Award for Best Actress for her role in Monster's Ball. The popularity of orange diamonds zoomed.

Pink Diamonds
Pink Diamonds are among the most sought after, rarest and most expensive. One of the reasons for this is the supply of natural fancy pink diamonds is extremely low.

Before the discovery of the Argyle Mine in the 1980’s, production of fancy pink diamonds was virtually non-existent. When Argyle went live, it quickly gained the reputation as the only reliable consistent source of high quality pinks in the world. With a near monopoly on the world’s pink diamond market, Rio Tinto began to invest in marketing and were responsible for driving demand even further.

The 'Pink Star' is a flawless 59.6-carat pink diamond. It was sold in 2003 for $ 83m but the buyer reneged.
The combination of extreme popularity with extreme scarcity makes for very pricy diamonds. Fine quality pink diamonds without modifying colors trail only red diamonds as the most expensive natural diamond color in the world.

Pink diamonds are graded as follows; Fancy Light Pink, Fancy Pink, Fancy Intense Pink, Fancy Vivid Pink

The Graff Pink is an emerald cut 24.78 carats, type IIa fancy intense pink diamond. It sold at auction for $ 46m in 2010.

In 2013, Christie’s sold the historic Princie diamond, a 34.65-carat cushion-shaped Fancy Intense Pink diamond, for $39.3 million.

‘The Sweet Josephine’ Fancy Vivid Pink diamond weighing 16.08 carats. $28.5 million at Christie’s in 2015.

Sotheby’s sold the 8.72-carat Fancy Vivid ‘Historic Pink Diamond’ for $15.9 million in 2015.

Purple Diamonds
Purple diamonds are the result of plastic deformation of a diamond's crystal structure, the same condition that produces red diamonds. In the case of purple diamonds, the color is the result of an unusually high amount of hydrogen.

Purple stones are as equally rare as red diamonds and command the same high prices when they (rarely) appear for sale.
Purple is the colour of royalty, of courage and honor. For hundreds of years, it was the colour of kings, as only royalty could wear purple. Purple heart medals are given to soldiers killed or wounded in action, as a recognition of their bravery and sacrifice.

Pure purple diamonds are nearly impossible to find. Most natural purple diamonds are lightly shaded with hints of pink, red, blue, gray or even brown, tinting the diamond slightly and lowering the overall perceived quality of the gem. Purple diamonds are most commonly found in Australian mines.
The Royal Purple Heart Diamond is the largest Fancy Vivid Purple diamond known to exist. The stone, believed to have originated in Russia, weighs 7.34 carats, has a clarity of I-1, and was cut into its perfect heart shape by the Julius Klein Diamond Corporation. The diamond's current owners are unknown.

Despite its name, the Supreme Purple Heart is a round brilliant cut. Its precise color grade is not known, nor is its clarity. Even its weight is estimated from two to five carats. Like the Royal Purple Heart Diamond, the Supreme Purple Heart's origins have not been confirmed, but most believe it was mined in the Amazon basin within the last 30 years. The diamond's color changes – when viewed from one angle, it appears deep purple, and from another angle looks deep red.
A fancy intense pinkish purple VS2 diamond debuted in 2014.

The 3.37-carat gem, named the “Purple Orchid,” has an asking price of $4 million, or nearly $1.2 million per carat.

Leibish & Co. purchased the South African diamond as a rough of more than 4 carats and spent four months cutting and polishing the gem.

Red Diamonds
Pure red diamonds devoid of secondary hues are the rarest in the world. The Argyle Diamond Mine is the only known significant source of pink and red diamonds, producing 95% of the world's supply. In the last 30 years of mining, Argyle has found a total of thirteen red diamonds.

Red diamonds are so rare there is little gemological information about them.

What is known is that crystal lattice defects showing stress lamination during the diamond's formation is the cause of the red color.
Red diamonds rose to prominence in April 1987 during a Christie’s auction where a 0.95 carat round brilliant cut Fancy Purplish Red diamond made a record-breaking $927,000 per carat.

In 1998, the New-York based William Goldberg Co. cut and sold the largest fancy red diamond known, a 5.11 carat shield-shaped Fancy Red diamond, the Moussaieff Red. It is one of the key attractions of the Smithsonian and is the world's largest known red diamond.
The Kazanjian Red Diamond is one of the three known red diamonds weighing more than 5 carats. The gem was discovered in the 1920s in Litchenburg, South Africa.

It was 35 carats uncut. A diamond broker paid eight pounds per carat for it.
The Rob Red Diamond is modest in size at 0.59 carats but it still holds a special place in the diamond world. The Rob Red is rated as the most intense red diamond ever discovered. The diamond is rated fancy purplish red by the GIA and is considered the most important red diamond in the world.

The De Young Red is 5.03 carats and graded as Fancy Brownish Red. It was found in South Africa in 1927. The stone was once mistakenly sold as a red garnet that was set in a hat pin.

A 3.15-carat fancy reddish-orange diamond sold for $2.09 million, or $666,200 per carat in 2012.

The Graff Purplish-red diamond, is a 2.26-carat, modified octagonal-cut, fancy purplish-red, SI2 clarity diamond. It sold for $ 2,646,000 in 2008.

A 1.92-carat, rectangular-cut, fancy red diamond sold for $ 3,252,675 in 2013. That price set a new price-per-carat auction record of $ 1,694,101
A heart-shape fancy red diamond ring by Moussaieff set a world auction record at Christie’s Hong Kong on November 25, 2014.

The 2.09 carat ring sold for $5,095,872, setting a new record of $2.44 million per carat.

Violet Diamonds
Pure violet diamonds without secondary modifying colors are impossibly rare, perhaps even rarer than purple diamonds. The presence of the trace element hydrogen in the atomic lattice is responsible for violet diamonds while purple diamonds are caused by plastic deformation. Violet diamonds and purple diamonds therefore consist of two separate colors.

Some industry professionals use the words “violet” and “purple” interchangeably. Violet diamonds are a distinct color group. Violet diamonds will appear more blue-grey to the eye while purple diamonds appear red or pinkish.

Fancy violet diamonds are assessed according to intensity of color, or a combination of saturation and tone. The more intense a diamond’s color saturation, the more it will be worth.

They are graded as follows: Fancy Violet, Fancy Intense Violet, Fancy Deep Violet and Fancy Dark Violet.
Violet diamonds of any kind are typically small and very rarely exceed one carat.
Natural fancy violet diamonds are extremely valuable. Even more valuable are those that are a pure violet color without any secondary modifying color. Modifying colors tend to devalue violet diamonds, but they are still exceptionally rare and will always be highly valued.

The Argyle Violet
The Argyle Violet, a 2.83 oval shaped violet diamond, is the dazzling centerpiece of the 2016 Argyle Pink Diamonds Tender. It is the largest violet diamond ever recovered from the Argyle mine.

Just 12 carats of polished violet diamonds have come from the Argyle mine over 32 years of mining.

The rough gem originally weighed 9.17 carats.

Yellow Diamonds

The Sun-Drop Diamond is the largest known Fancy Vivid Yellow pear-shaped diamond at 110.03 carats. It sold in November 2011 for $12.4m.
For centuries the most prized diamonds have been pure white or deep coloured blue, red, pink, or green. Yellow diamonds have not been highly prized, and have been seen as inferior to white diamonds.

Yellow diamonds are rare and are much more appreciated today, as celebrities sport the gems regularly. The term 'canary' diamonds has been incorporated into the modern term “Fancy Yellow”. The GIA grades natural Fancy Yellow diamonds into 4 main qualities, Fancy Light, Fancy Yellow, Fancy Intense and Fancy Vivid.

The Graff Fancy Vivid Yellow diamond weighs 100.09 carats and is graded VS2 clarity. It set a world auction record for a yellow diamond in 2014.– $16,347,848

75.56-carat cushion modified brilliant-cut Fancy Vivid yellow diamond - $ 3.8m
Yellow diamonds range from a pale delicate yellow to a pure rich canary or sunflower yellow. Yellow diamonds may also have secondary shades, primarily orange or brownish, which affect the clarity of the color. Greenish or pinkish secondary shades are extremely rare and extremely valuable. Yellow diamonds are graded similarly to white diamonds, with the exception of color and cut.

Unlike white diamonds, which are prized on the lack of color, yellow diamonds are graded for clarity of color. Fancy Vivid Yellow grades are extremely rare.

The Tiffany Yellow Diamond was a 287.42 carat rough and is one of the largest yellow diamonds ever discovered. It was cut to 128.54 carats in a cushion shape with 90 facets to bring out the brilliance of the stone.
The Florentine Diamond is almost 140 carats, light yellow with green undertone diamond, this diamond belonged to the Medicis, one of the most powerful families in Europe. In 1743, it was in the hands of the Hapsburgs, and the Emperor Francis I wore the Florentine in his crown. In 1918, following the fall of the Hapsburgs, the stone followed the family to exile in Switzerland and vanished.

The Incomparable is the largest yellow diamond and third largest diamond in the world. The 407.48-carat gemstone is described as a golden-coloured kite-shaped diamond, graded as flawless and fancy deep brownish-yellow by the GIA.
The De Beers diamond. Weighing 234.65 carats, the De Beers is the seventh largest faceted diamond in the world. After its display in Paris the Maharaja of Patiala bought the stone.

In 1928 Cartier of Paris set it as the centerpiece of a ceremonial necklace that came to be known as the Patiala Necklace.

Argyle Pinks

Australia's Argyle Diamond mine is the world's primary source (95%) of rare pink diamonds. Pink diamonds are at very least 20 times the price of an equivalent white diamond. This places them in the rarified air of most highly concentrated form of wealth on Earth.

After being cut and polished at Rio Tinto’s diamond cutting and polishing factory in Perth, exceptional pink diamonds from each year's production are sold individually at 'tenders'.

The diamonds average around a carat each with 40 to 50 carats in total sold each year. Of every million carats of rough diamonds produced at the Argyle mine, less than one carat is suitable for sale in one of the tenders. Prices can range from US $100,000/ct to US$1,000,000/ct and far beyond.
