Nice specimen - Polished Chrysocolla on Malachite - Height: 147 mm - Width: 85 mm- 1095 g

This specimen of chrysocolla on malachite comes from the Congo, one of the world’s most famous regions for its copper deposits and for the variety of secondary minerals that derive from them. The formation of this sample dates back to ancient geological times: the oxidation processes of the large copper-bearing deposits, started millions of years ago, favored the crystallization of copper carbonates and silicates which, layer after layer, gave rise to these spectacular concretions. Malachite, with its dark green bands and typical botryoidal structure, provides the solid base of the piece. On it, chrysocolla developed, covering the surface with an intense blue-turquoise color, traversed by delicate natural networks and by silvery veins due to metallic residues. The union of the two minerals creates a striking chromatic contrast, telling the story of the continued transformation of matter in the oxidized copper deposits. This sample, with an aesthetic of rare beauty, is a geological document that testifies to the meeting of mining processes and the deep times of the Earth. An ideal display specimen for natural history collections, mineralogical museums, or for anyone looking to enrich their spaces with a mineral that blends science and nature’s art into a single form.
