Unlike any other diamond that exists, the Chameleon variety changes color temporarily, hence the name. While the base color is an olive tone like this 1.07 Carat cushion cut from Leibish & Co., there are multiple hues. Needless to say, it’s very unusual and unique. In our years of experience, Leibish & Co. offers the best prices and overall customer experience in the Fancy Color Diamond market. Additionally, we have found that the craftsmanship exhibited by Leibish & Co provides the highest level of expertise in bringing out the color of the stone when it’s set in jewelry.
Peter Kaplan noticed the first recorded chameleon diamond in 1943 when he saw a change in a diamond that was resting on a hot polishing wheel. Since then, chameleon diamonds have received a category of their own and are considered more unique and valuable than similar colored diamonds that don’t change color.
Gemologists still aren’t certain as to what causes the chameleon to embody its unique color-changing characteristics. High concentrations of hydrogen in the atomic structure may be a reason, as well as its impurities of nitrogen and nickel. Still, other gemologists believe that the gemstones have phosphorescent and luminescent qualities. The chameleon diamond’s color-changing property is known as thermochromism when it responds to heat and photochromism when it reacts to light.
”Under normal conditions, the color of chameleon diamonds is typically grayish yellowish green to grayish greenish yellow. But, when heated up to 150° C (302° Fahrenheit) — or exposed to light after prolonged storage in the dark — a remarkable color change happens.” Gemological Institute of America (GIA)
A color changing diamond sounds bizarre—and it is. But the color-changing aspect itself is not permanent. Still, chameleon diamonds are the only diamonds that contain the ability to have their color altered naturally, even if only temporarily. When exposed to heat or hidden from the light, the chameleon often changes from a lighter yellowish tone to a darker greenish hue.
Chameleon diamonds can be broken down into two types: Classic and Reverse.
The Classic variety refers to most chameleon diamonds. Classics turn from an olive green color—generally some combination of gray, yellow and green—to a lighter orangey yellowish hue. The duration varies how long the new color is visible but can last anywhere from a few minutes to over an hour.
Reverse chameleons are stones that display the opposite behavior. They are lighter yellower stones that can temporarily become darker and greener when stored in a closed, dark spot. In contrast to Classic chameleons, their color is not affected when treated with heat.
In order to spot a genuine chameleon diamond, you’ll need to know a few of its main characteristics. For starters, chameleon diamonds are not found in the typical stronger color intensities such as Vivid and Intense. Instead, chameleons are either Fancy, Fancy Deep or Fancy Dark.
A chameleon diamond possesses diamond fluorescence as well as a color combination. The hues always include at least two of the following: green, yellow, gray and brown.
Common color combinations for chameleon diamonds include gray-yellowish, grayish-yellowish, gray-greenish, green-yellow, brownish-greenish and brownish-yellowish. Many other combinations exist; you can basically find any combination of green, yellow, gray and brown.
Chameleon diamonds aren’t just a source of interest for diamond collectors, they’re also a scientific enigma. The only way to obtain a color-changing gem is by purchasing a chameleon diamond. Since they are quite rare, they are generally priced more than most colorless diamonds—yet they are far more affordable than the higher priced color diamonds like pink and orange.
In general, Fancy Deep or Fancy Dark chameleons are more desirable because their color is stronger and the color change effect is usually more pronounced.
Also, as is the case with all diamonds, the price of chameleon diamonds goes up drastically with increased size. This phenomenon is even more pronounced with chameleons, since large stones of this type are extremely rare.
If you’re seeking a diamond that’s less permanent, you may want to consider the chameleon diamond. While the base color is an olive tone like this 1.07 Carat Cushion Cut from Leibish & Co., there are multiple hues.
Diamonds Pro helped us pick a diamond, according to our budget and a few other criteria. We ended up buying a loose diamond from James Allen. We felt that we got very good value for money. The diamond was appraised by another jeweler where we live, confirming its characteristics and value. Finally, we had the diamond set in a ring by a local jeweler, and we’re very pleased with the result! Thank you Diamonds Pro 😊…see more
