What Determines the Value of a Chameleon Color Diamond


The Color

Unlike most other fancy color diamonds, chameleon coloration is not entirely understood. The color that exists in chameleon diamond is classified as a natural color all on its own. Additionally, the photochromic and thermochromic behavior cannot be duplicated and it is impossible to cause this effect on other diamonds. Photochromic behavior enables the stone to briefly change to a darker color when stored in a dark place for a longer period of time and thermochromic behavior enables the stone to briefly change to a darker color when heated. As the stone cools or is exposed to light once again, it returns to its lighter color. This effect happens in what are known as "Classic" Chameleon diamonds. Their are also "Reverse" Chameleon diamonds where the effect happens within a naturally dark color chameleon diamond and when exposed to heat or dark, it shifts to a lighter color, only to return to its stable dark color when cooling off or exposed to light.

All diamond colors are created by the compound elements absorbed into the structure of the stone throughout its formation. However, to this day, there is no known consistent elements that exist within chameleon color diamonds. Some scientific evidence points to possible causes of the chameleon color being caused by the presence of hydrogen in the diamond lattice structure; also nickel is sometimes found in chameleon diamonds which appears to modify or intensify the effects of the hydrogen.

There is some debate as to whether being included in the category of a chameleon diamond requires changes either by being exposed to heat or dark, or whether only photochromic behavior is the sole determining factor for the diamond’s categorization.
