Key Characteristics of Chameleon Diamonds:
Colour Change:
Chameleon diamonds typically shift from an olive green or grayish-green hue to a yellow or orangey-yellow shade when exposed to heat (approximately 150°C) or left in darkness for an extended period.
Once cooled or exposed to light again, they revert to their original colour.
Thermochromic & Photochromic Properties:
The colour change can occur due to both heat (thermochromism) and darkness/light exposure (photochromism), making them unique among diamonds.
Rare Chemical Composition:
Scientists believe the colour change is due to a combination of hydrogen, nitrogen, and possibly nickel impurities within the diamond’s crystal structure.
Not a Fancy Colour Diamond:
Unlike standard fancy colour diamonds, which have a fixed hue, chameleon diamonds possess a dynamic, temporary colour change.
Value & Rarity:
Due to their scarcity, chameleon diamonds are highly prized by collectors and diamond enthusiasts.
