Color in precious stones: Chameleon Diamonds

According with the GIA when a diamond falls outside of GIA’s (colorless) D to Z color scale, it is considered a colored diamond (sometimes called a fancy color diamond). This includes all colors other than colorless to light yellow or brown . There are diamonds with enough color to be considered Fancy Color. We can find almost any color, the most rare are red, green, purple, orange, pink and blue.

Special Diamonds

Chameleon Diamonds are incredible are fascinating gemstones, as the name says these diamonds can change color when are exposed to heat for an extended period of time, some also change their colors when are exposed in the dark.

Why is the change:

The nature of the color change is still a mystery, studies from GIA suggest that the cahnge ocuursthrou shifts in the broadvisible absortionbandsthat create the color. When extreme heat is applied in regular diamond (not chameleon) the color can permanently change.

We can see at the pictures the color change at 300 C 200 C and 75 C, from light brown to dark green. But dont worry the color will be back!
