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 arise from them. The formation of this specimen dates back to ancient geological times: the oxidation processes of large copper-bearing deposits, begun millions of years ago, favored the crystallization of copper carbonates and silicates which, layer by layer, gave rise to these spectacular concretions. The malachite, with its dark green bands and the typical botryoidal structure, forms the solid base of the specimen. On it, chrysocolla developed, coating the surface with an intense blue-turquoise color, crossed by fine natural reticulation and by silvery veins due to metallic residues. The union of the two minerals creates a striking color contrast, telling the ongoing transformation of matter in the oxidized copper ore deposits. This specimen, with an aesthetic of rare beauty, is a geological document that testifies to the meeting between mining processes and the deep times of the Earth. An ideal display specimen for natural history collections, mineralogical museums, or for those who wish to enrich their spaces with a mineral that blends science and natural art in a single form.
