ABOUT THE SPECIMEN

Here's a rich specimen of malachite, composed of numerous stalactitic columns with a gorgeous chatoyancy, as well as a sparkling glimmer along its edges. Adding to the specimen is the hand-carved wooden base that comes with it. The base is set to depict an east Asian countryside with intricate houses, trees, and animals, with the malachite as the centerpiece, representing a skarn mountain covered with greenery. Seeing how many specimens were shipped directly from this locality to China, it was most likely carved there. There's little doubt that some of the best - if not the best - primary malachite has come from the Democratic Republic of the Congo, and it’s all the better when you get an example that displays as well as this.

MORE INFO

The Star of the Congo operates within the Katanga Copperbelt's Pan-African Lufilian fold-and-thrust belt, where a ScienceDirect study confirmed that malachite formed through REE-depleted groundwater environments percolating downward through oxidized copper sulfides, with carbonate ions from dissolving dolomitic host rock combining with dissolved copper to precipitate the secondary carbonate in open karstic cavities. What distinguishes L'Étoile du Congo from most other Katanga malachite sources is a recurring production of primary crystallized malachite - crystals that formed their own habit directly rather than as pseudomorphic replacements of azurite, displaying triangular to diamond-shaped crystal outlines to roughly 1 cm over rounded emerald-green aggregate bases. A 2016–2017 pocket produced a particularly unusual two-generation primary malachite: earlier deep evergreen crystals overcoated by a second generation of velvety botryoidal malachite, the contrast in color and texture on a single piece being without close parallel in the Katanga district. Chrysocolla and malachite stalactite combinations - where teal chrysocolla either underlies or overlies botryoidal malachite in concentric layers - represent a third distinct expression from the mine. The variety of mineralogically distinct malachite expressions from a single locality, rather than any single find, constitutes the mine's primary scientific and collector significance.
