What Are Chameleon Diamonds?

The color of these diamonds change from grayish yellowish green to grayish greenish yellow under normal conditions. However, when they are heated to 150 degrees (302 Fahrenheit) or moved to a brighter place after being in the dark for a long time, their color changes abruptly from their normal color to an intense brown or orange yellow or yellow.

These stones display a color change for around 15 minutes when exposed under UV light for 60 seconds. Some of these even emit fluorescence for at least around 1 hour after the light is turned off.

He bought a light yellow diamond which changed to a dark green color after some time. The man took the stone back demanding a refund.
