[On sale May 9th, 10 PM JST] Turkish Color Change Diaspore 1.085ct Loose Gemstone
Diaspore, a rare gemstone, sometimes sold under the name "Zultanite." It exhibits a wide range of colors, from subdued to lovely hues. Gem-quality specimens are rare, and because they are difficult to cut, they do not easily circulate as finished jewelry. This is a rare color-change type. It would make a great addition to your collection. Enjoy the color change by using a red-spectrum color-change penlight and a white-spectrum penlight.
This is a color-change diaspore by Sri Lankan lapidary artisan, Mr. Sanje. You can enjoy the fantastic colors that change expression depending on the light source. It features a careful and beautiful cut with minimal color loss even when viewed from the front.
