This week I prepare great minerals for You. A striking specimen combining deep black heterogenite with vibrant blue-green chrysocolla in a botryoidal and velvety texture. The contrasting colors and natural, wave-like formation make it an eye-catching piece for any serious collection. Collected from the famous copper-cobalt deposits of Katanga, Democratic Republic of Congo, known for producing world-class secondary copper minerals. Perfect for collectors seeking aesthetic and mineralogical value. Condition as on pictures. Very aesthetic specimen much better in person. 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.
