From our selection of collectible minerals, we are pleased to offer a splendid polished specimen of Malachite from the L'Etoile du Congo Mine, Lubumbashi, Haut-Katanga, Democratic Republic of the Congo.

It also features a smooth, polished surface that highlights the characteristic dark and light green concentric bands typical of Malachite’s botryoidal structure, with well-defined eye-like patterns and an attractive decorative effect. These features enhance its aesthetic value and mineralogical significance.
The specimen stands out for its crystal quality and overall aesthetic balance, with features that enhance its natural structure and visual impact.

Malachite is a copper carbonate, Cu2CO3(OH)2, whose intense green color comes from the presence of copper in its crystal structure. It typically forms in the oxidation zone of copper deposits through the alteration of other copper minerals such as chalcopyrite. The Haut-Katanga region of the Democratic Republic of the Congo has historically been one of the world’s most productive areas for this mineral, thanks to its extensive copper and cobalt deposits. The characteristic botryoidal structure with concentric bands, visible once the stone has been cut and polished, results from the successive growth over time of layers of varying thicknesses and shades of green.

This is an ideal specimen for mineral collections and display, and for anyone who appreciates the natural beauty of minerals, including in crystal therapy and lithotherapy, according to the properties traditionally associated with this mineral species.

All minerals are 100% natural and untreated, with only very rare exceptions, which are always stated in the description. The photographs are taken under professional lighting to showcase the colors and details as clearly as possible; however, slight variations in color may occur depending on the device or ambient lighting.
