Today great specimen : An exceptional specimen featuring deep emerald-green dioptase crystals elegantly intergrown with velvety malachite. The sharp crystal forms and rich luster make this piece highly aesthetic and ideal for any advanced collection. Its striking contrast and intense color are characteristic of the Tenke locality, famous for producing some of the world’s finest copper silicates. A rare opportunity to acquire a specimen with such strong visual presence and mineralogical interest. Top qulity with extra crystals. 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.
