The Colored Diamond Exchange: A Description Of The Rarest Colored Diamonds

It is widely recognized that the rarest colored diamonds in the world are red and green. These types of stones rarely become available to the public and when they do they often sell for $500,000 to $1 million per carat.

Natural green diamonds are extremely rare. The most famous green diamond is the Dresden Green in Germany. Although this particular green has a strong color, most green diamonds are pale in color with light tones. The green color in diamonds is caused by natural radiation of the earth, probably by uranium ore. Pure green diamonds are known to occasionally come from parts of Brazil but only a few green diamonds are available on the market every year.

The earliest known red diamond was the 1-carat Halphen Red. The two most famous reds today are the .95 Hancock red and the 5.1-carat Moussaieff Red. Both of these stones are considered to be worth well over a million dollars a carat. Some say there are only 50 red diamonds in the world. Red diamonds are known to come from Australia and at the last four Argyle pink diamond tenders, two red diamonds have been sold, including a one carat red last year. It is not known exactly how red diamonds form in nature but it is thought that a similar procedure to pink intense diamonds requiring nitrogen and pressure creates rare red diamonds.
