When Jewelry meets Science : the Chameleon Diamond

[Pierre Tavlitzki]

The colored diamonds join science. An extremely rare variety known as "chameleon" was first described in 1943. The guarantee of natural diamond is still ensured by the fact that its properties have not been explained and can not be replicated in the laboratory.

It is a green diamond with color changing after a prolonged stay in the dark or when it is slightly heated. It then comes back to its original color.

The gem that Christie's will sell on April 22 in New York is important: 19.13 carats. This is the biggest briolette shaped chameleon diamond ever analyzed by the Gemological Institute of America. This curiosity of nature has been made a pendant for a necklace, and estimated 800 K $.

Do not confuse curiosity and jewelry: the chameleon diamond has not been sold.

There is consolation in the alert, at $ 4 million premium included for a purplish pink diamond of 30 carats mounted on a ring in rose gold and platinum.
