6.9 x 5.4 x 1.6 cm. This vivid, sparkly yellow specimen features an incredibly rich coating of the very rare species jouravskite, in a carpet of microcrystals completely covering the (calcite?) matrix. This is a rare hydrated, calcium, manganese sulfate, carbonate that comes out only rarely from the Kalahari Fields.

MD-54384 - Brucite, Jouravskite - - Archived N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa miniature, 3.9 x 2 x 1.9cm
This is definitely one of the lesser known species from N’Chwaning, which arguably produced the finest rhodochrosites in the world. However, who wants the common stuff, eh? This new find of lovely, translucent, pastel-colored brucite is just incredible for the species. Very nearly a floater, complete all around save for a small matrix attachment seam along the back, this is a steller miniature with great aesthetics! The yellow dusting is a bonus - microcrystals of the rare mineral Jouravskite 3.9 x 2 x 1.9cm
