Chameleon Diamonds & Their Unique Colour-changing Properties

Blog

Chameleon diamonds have the natural ability to temporarily change colours from hues of green to hues of yellow or the other way around depending on whether the Chameleon diamonds are considered to be 'classic' or 'reverse'. The special properties of Chameleon diamonds make them a wonderful choice for engagement rings, wedding rings and more.

The Fundamentals Behind the Colour Change

The ability of the Chameleon diamonds to change colours is known as thermochromism and photochromism. Although scientists have not been able to fully explain the unique phenomenon behind the colour change, the colour changing abilities of Chameleon diamonds may be attributed to the fact that these diamonds contain unusually high concentrations of nickel, nitrogen, and hydrogen within their crystalline structures.

Other experts claim that the colour changing abilities of Chameleon diamonds may be due to the fact that these diamonds have luminescent and phosphorescent properties thanks to their unique crystalline structure. The colour changes when the diamonds are exposed to varying spectrums of light and to fluctuating temperatures of heat.

Chameleon diamonds come in 4 different colours—green, yellow, brown and gray—and contain at least two overtone colours. This colour-changing phenomenon does not happen in pure coloured diamonds.

Difference Between Classic and Reverse Chameleon Diamonds

Classic Chameleon diamonds naturally possess a light hue, but its colour temporarily changes for short periods of time to a darker colour when heated and when stored in dark places for long periods of time. When the Chameleon diamonds cool off or are exposed to light, their colours gradually become lighter once again.

The opposite happens for reverse Chameleon diamonds. Reverse Chameleon diamonds are found in darker stable hues, and the colour changes temporarily to lighter hues when stored in dark places for long periods of time. Unlike classic Chameleon diamonds, reverse Chameleon diamonds do not change colours when exposed to fluctuating temperatures.

Chameleon diamonds are beautiful and their colour changing properties make them quite unique, as this behavior cannot be replicated with any type of treatment. Every Chameleon diamond is unique, and there are many colour combinations that can be found. Unfortunately, Chameleon diamonds are quite rare in comparison to other alternatives. As a result, they can be quite expensive, and often come with hefty price tags attached to them.

Ancient Jewelry: Ideas, Decorations and Styles

Hi, my name is Claire, and I have been interested in ancient times since my mum used to whisper Greek myths to me as bedtime stories. As I got older, I began to make and design my own jewelry. I started as a kid with strings and beads and worked my way up to metal working and jewel setting. I began to research ancient jewelry, and I let it inspire and influence my designs. I also learned how to integrate antique jewelry with new ideas. If you are a jewelry lover, please explore the posts on this blog and enjoy!
