 Aurora Diamond Collection The Aurora Diamond Collection of natural color diamonds is one of the most comprehensive diamond collections in the world. It was on public display at the American Museum of Natural History in New York from 1989 to 2005 in the Morgan Hall of Gems. The Aurora Collection was the centerpiece for the 1998 exhibition The Nature of Diamonds organized by the American Museum of Natural History which toured Japan, Canada and the U.S. In 2005 The Aurora Collection was invited to participate in the exhibition Diamonds organized by The Natural History Museum of London. At that time 36 new specimens were added to the original 260 diamonds. Today The Aurora Collection consists of 296 diamonds weighing a total of 267.45 carats. This article is about the gemstone. ...

All the colors of the spectrum that diamonds exist in are represented in various shapes, saturations and modifiers including blue diamonds, pink diamonds, red diamonds, green diamonds, orange diamonds, purple diamonds, violet diamonds, yellow diamonds, olive diamonds and brown diamonds. Also represented are color changing chamelion diamonds. The Aurora Collection was put together by Alan Bronstein and Harry Rodman over 25 years.

Additional Information The Colors of Diamonds
Natural color diamonds, also referred to as "fancy color diamonds" exist in many hues, tones and saturations. The strength of color is categorized by the Gemological Institute of America (GIA) as:

Color in diamonds is a function of absorption and reflection of light. When a diamond appears colorless, white light or daylight (all the colors of the spectrum combined) enters the diamond and are all absorbed so no color is reflected back to the eye. When a diamond appears to have a color, white light entering the stone is absorbed except for the color that appears to the eye. Colorless diamonds are pure carbon.

Blue diamonds are caused when boron atoms are trapped in the diamonds atomic structure, which alters the absorption spectrum of the stone. Blue diamonds are found most often in South Africa and the extinct mines of India. Blue diamonds tend to be modified by gray or green. The color of blue diamonds can be described as sapphire, sky, blueberry and robin’s egg.
The most famous blue diamonds are The Hope Diamond and The Heart of Eternity Diamond.

Diamond color - Pink

Pink diamonds are caused by Plastic Deformation; a twisting of the atomic structure of the carbon atoms during the formation of the diamond in the earth which alters the absorption spectrum of the stone. It appears in the stone as grain lines similar to grain in wood. It does not alter the nature of the diamond only its color. Pink diamonds are found most often in Australia, South Africa, and Brazil. Pink diamonds tend to be modified by purple, orange or brown. The color of pink diamonds can be described as bubble gum, blossom, salmon and shell.
The most famous pink diamonds are The Agra Diamond and The Steinmetz Pink Diamond.
Diamond color - Yellow

Yellow diamonds are caused when nitrogen atoms are trapped in the diamonds atomic structure, which alters the absorption spectrum of the stone. Yellow diamonds are most often found in South Africa, Russia, and most recently in Canada. Yellow diamonds tend to be modified by orange, brown or green. The color of yellow diamonds can be described as lemon, canary, champagne and chartreuse.
The most famous yellow diamonds are The Tiffany Diamond and The Allnatt Diamond.

Red diamonds are caused by Plastic Deformation; a twisting of the atomic structure of the carbon atoms during the formation of the diamond in the earth which alters the absorption spectrum of the stone. It appears in the stone as grain lines similar to grain in wood. It does not alter the nature of the diamond only its color. Red diamonds are most often found in Australia and Brazil. Red diamonds tend to be modified by purple or brown. Their colors can be described as wine, cranberry, strawberry, and garnet.
The most famous red diamonds are The Moussaieff Red Diamond and The Hancock Red.

Diamond color - Green

Green diamonds are caused by natural radiation over millions of years in the earth which alters the atomic structure of the diamond thus altering the absorption spectrum. Green diamonds can also be caused by hydrogen trapped in the diamonds atomic structure. Green diamonds are most often found in Guyana, Brazil, South Africa, and the extinct mines of India. Green diamonds tend to be modified by yellow or blue. Their colors can be described as grass, emerald, sea foam, and apple.
The most famous green diamonds are The Dresden Green Diamond and The Ocean Dream Diamond.

Diamond color - Orange

Orange diamonds are caused when nitrogen atoms are trapped in the diamonds atomic structure, which alters the absorption spectrum of the stone. Orange diamonds are most often found in South Africa and Brazil. Orange diamonds tend to modified by yellow or brown. Their colors can be described as pumpkin, cantaloupe, amber and brandy.
The most famous orange diamond is The Pumpkin Diamond.
Diamond color - Purple

Purple diamonds are caused by Plastic Deformation; a twisting of the atomic structure of the carbon atoms during the formation of the diamond in the earth which alters the absorption spectrum of the stone. Purple diamonds are found most often in Russia. Purple diamonds tend to be modified by pink or brown. Their colors can be described as lilac, amethyst, grape or plum.
Diamond color - Violet

Violet diamonds are caused by hydrogen atoms that are trapped in the diamonds atomic structure, which alters the absorption spectrum of the stone. Violet diamonds are found in Australia. They tend to be modified by gray or blue.
