Description from the seller
Massive malachite – Botryoidal mineral form – Old provenance Congo (Katanga) – 1,715 kg
Superb massive malachite nodule featuring a very characteristic botryoidal mineral form, composed of rounded globules naturally formed by the precipitation of copper carbonates in rocky cavities. This morphology, known as 'in clusters,' is one of the most sought-after signatures of malachite from Central Africa. The piece comes from an old succession of expatriates settled in Congo, probably from the Katanga mining region, renowned for over a century for its dense, varied malachites of an exceptional green. The outer crust, dark and slightly ferruginous, displays shades of black-brown mixed with greenish touches on the surface, while a sawn face reveals a dense internal malachite, deep green, with veins and lighter marbling typical of massive deposits.
The tradition of malachite blocks brought back by expatriates from Katanga dates back to the 1950s–1980s and is now a highly valued marker of authenticity. This specimen clearly exhibits these characteristics: entirely natural malachite, unpolished (except for the cut to facilitate presentation), free of modern treatments, and preserved in its raw state. The botryoidal appearance is particularly well developed, with several fused lobes forming a unique organic geometry.
Overall very good condition for a raw specimen of this size. The crust shows roughness, irregularities, and natural oxidation zones, without major chips. The cut reveals traces of ancient tools and fine scratches from origin, with no impact on mineralogical or decorative quality. No structural impact, no restoration.
Dimensions: 7.8 cm in height – 12.2 cm in width – 11.9 cm in depth.
Weight: 1,715 g.
Ancient botryoidal mineral form, very representative of the historical productions of Katanga. An ideal piece for collectors of copper minerals, old African provenance specimens, or large natural botryoidal samples.

Specific packaging and insurance included in the delivery price.
