Fancy colored diamonds have captured the fascination of the jewelry industry for their beauty, rarity and unique hues. While all fancy colored diamonds are distinguished for their colorful splendor and radiance, chameleon diamonds are the only natural colored diamonds with the ability to change color. A captivating mystery, there is no certain scientific reason for this phenomenon, but it is believed to be due, in part, to the reaction between the diamond's hydrogen and isolated nitrogen atoms interacting when "excited" by increased temperatures and changes in UV light rays. This fascinating process cannot be duplicated, and there exists no known treatment to cause the chameleon effect in other stones.
