Today great specimen : A breathtaking specimen featuring vivid emerald-green dioptase crystals perfectly set on a matrix of creamy calcite and velvety malachite. From the world-famous Tenke Mine, this piece embodies the intensity and elegance for which Congolese dioptase is revered. The lustrous, transparent crystals glow with an almost gem-like fire, creating a stunning contrast against the pale background. A collector’s masterpiece — both mineralogically important and visually mesmerizing. Colors are much closer to emerald - green. Dioptase and malachite always looking bad on pictures. In reality they are much prettier. Very aesthetic specimen much better in person. I'm trying to show You specimens and crystals hand selected, not usual, beautiful and pricey. condition as on pictures. Color is very difficult to reproduce in the pictures. Some pictured specimens show slightly different shades that seen with a human eye. Generally in my opinion the colors in reality are slightly prettier.
