Rhodochrosite, Quartz, Manganite
Thumbnail, 2.5 x 2.25 x 2.25 cm
N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa
This is a brilliantly sparkling specimen with tiny, jet-black manganite crystals perched on sparkly quartz druse, itself coating liberally a cluster of basally-terminated rhodochrosite crystals. The contrasts are striking! The rhodo formed as a "cap" of some kind upon an earlier generation of rounded rhodochrosite or calcite, as it has a rounded indentation in the base. This is one of the most breathtaking rhodo thumbnails I have seen. Sure, there are pieces with bigger crystals, and gemmier, but what a combo....! 2.5 x 2.25 x 2.25 cm
