Demesmaekerite xls, Chalcomenite; Musonoi, Shaba, Democratic Republic of Congo; Min; unique piece
Demesmaekerite crystals and Chalcomenite from Musonoi, Shaba, Democratic Republic of Congo – miniature specimen as unique piece
This miniature specimen features Demesmaekerite crystals together with Chalcomenite from Musonoi in the Shaba region of the Democratic Republic of the Congo. The piece stands out with its intense coloration, showing vivid green and blue tones typical of copper bearing secondary minerals. The surface appears finely crystalline to velvety, creating a lively and high contrast appearance.
The Demesmaekerite crystals are visible as fine, partly radial crystal aggregates that clearly stand out from the matrix. They are complemented by Chalcomenite, which appears in lighter, slightly lustrous areas and enhances the mineralogical diversity of the specimen. The crystals are clearly recognizable and give the piece an attractive and richly structured surface.
Geology & Origin
Demesmaekerite is a rare copper uranium mineral that forms in the oxidized zones of copper deposits. It develops as a secondary mineral through the alteration of primary ores under oxidizing conditions and is often associated with other copper and uranium minerals.
Chalcomenite is a hydrated copper selenite mineral that also occurs in oxidized zones of ore deposits and forms through secondary processes.
The Musonoi deposit in the Katanga Copperbelt is one of the most important localities for rare secondary minerals worldwide. The complex geochemical conditions of this region result in an exceptional variety of vividly colored and highly collectible mineral formations.
