The green diamond is the second rarest variety of color diamonds which only number one out of every 10,000 diamonds occurring in nature. The color span of the green diamond ranges from pale green, to yellowish-green, to gray-blue green, to vibrant green, and these color diamonds are graded as fancy, fancy intense and fancy vivid. A fancy green diamond can be sold for $60,000-$125,000 per carat; fancy intense--$125,000-$150,000 per carat; and the price of a fancy vivid green diamond starts at over $250,000 per carat.
Millions of years of naturally occurring radioactivity lead to the creation of a natural fancy green diamond. Central and South Africa and Australia contain the alluvial secondary deposits where a green diamond may be discovered. Their extraordinary rarity makes them extremely valuable.
Like all fancy color diamonds, the cut of the green diamond also strives to accentuate its color and make the most of its brilliance. Although the round cut is the most popular cut for the natural fancy green diamond, it also lends itself to princess, emerald, Asscher, marquise, pear and cushion cuts.
Famous diamonds in the green diamond family:
The Dresden Green Diamond — Mined in India, its weight of nearly 41 carats, makes the apple-colored Dresden Green Diamond the largest green diamond in the world. After it was examined by the Gemological Institute of America (GIA) in 1988, its size was determined to be 29.75 x 19.88 x 10.29 mm and its weight almost 41 carats, and the GIA ruled that those two factors in addition to the Dresden’s unusual green color and wonderful transparency make it one of the world’s greatest diamonds.
Its name refers to the capital city of Saxony, where it was displayed as part of the collection of the Green Vault from 1768 to 1942. Its earliest history can be traced to London in 1722, when it was shown to King George I, and a record from 1726 shows it was offered to King Frederick of Saxony by a London merchant who tried to sell it for ?30,000. However, its first royal owner was Frederick Augustus II, who purchased the green diamond from a Dutch merchant in 1741. The diamond was first set by a court jeweler in the Decoration of the Golden Fleece, from which it was removed in 1746, to be placed instead in another Golden Fleece ornament. After this too was broken up, the pear-shaped green diamond was placed as an ornament in a hat clasp with two large colorless diamonds, and many smaller stones, and is now on display in the Albertinium Museum in Dresden.
The Gruosi Green Diamond — The rough stone of this green diamond came from South Africa, and in its original rough form weighed nearly 100 carats; its weight after cutting was 25 carats, which makes it the second largest green diamond in the world.
Owned by the Swiss jewelry house De Grisogono founder, Fawaz Gruosi, this rare green diamond has been set in a gold band amid 382 smaller diamonds, totaling 7 carats. The green diamond itself is free of nitrogen impurities and is determined to be in the naturally irradiated category of type IIA diamonds, as evidenced by the even distribution of its green color within the diamond’s crystal formation. This diffusion of color is extremely rare in the general category of color diamonds, and is particularly rare in a green diamond.
The Ocean Dream Green Diamond — This green diamond, weighing 5.1 carats, is considered one of the rarest and most precious diamonds in the world, despite its relatively small size. The scientific analysis techniques of the GIA determined its color, the result of long-term exposure to natural radiation, to be Fancy Deep Blue-Green which is a one-of-a-kind designation among fancy color diamonds.
There is no provenance for this rare green diamond, which is unusual since a diamond’s value may derive from its history in addition to its other attributes. All that is known is that it was mined in central Africa. Also a mystery is how the current owner, the New York-based Cora Diamond Corporation, acquired the diamond. The Ocean Gem Green Diamond was part of the Smithsonian Institution’s 2003 “Splendor of Diamonds” exhibition along with diamond legends, the Heart of Eternity and De Beers Millennium Star.
