Today great specimen : A highly aesthetic specimen featuring emerald-green dioptase crystals beautifully set against a vivid blue layer of shattuckite, accented by creamy calcite. The strong color contrast makes this piece a true eye-catcher and a desirable addition to advanced collections. A fine quality combination from Tenke, Democratic Republic of Congo. 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.
