I have heard about rare colored diamonds before but I was recently introduced to the concept of chameleon diamonds. The chameleon is an extremely rare stone, it has a stable color of greenish yellow but then they can change color, going from bright yellow or orange. Exposure to heat or a few hours of dark storage are the catalyst for the change which only lasts for a short time. The stones are extremely rare and, as a recent article in the Financial Times attests, prized by the truly obsessed collectors. The Leviev boutique ,which specializes in intensely colored stones, has two such precious jewels each set into a unique setting meant to showcase the stone's qualities. The one shown here is a .73 carat cushion fancy deep grayish yellowish green phenomenal diamond flanked by two half moon and pave set diamonds, all set in platinum. It sells for $33,600.

A truly amazing stone is after the jump, an exceptional radiant cut 8.04 carat fancy dark grey green chameleon diamond surrounded by pink pave diamonds and set in i8 carat pink gold. The size and rarity of the main stone push the price of this beauty up to $2,100,000.
