A chameleon diamond is a rare natural colored diamond that can temporarily change color in response to environmental conditions, particularly heat or light. Chameleon diamonds can change from a green-like color to a yellow or orange hue, or vice versa. The color change is temporary, and the diamond usually reverts to its original color when the environmental conditions return to normal. 🦎 Just like all fancy colored stones it goes from Faint to Fancy deep.
