N'Chwaning II Mine, Kalahari Manganese Field, Northern Cape, South Africa
Size: 5.7 x 4.6 x 2.8 cm (Small Cabinet)
The specimen is a botryoidal formation of strawberry-brown olmiite. One larger crystal ball to 2.9cm creates a point of visual interest in the intergrown assembly of rounded forms. The ball formation are the outcome of smaller tetragonal prismatic crystals growing together in slightly radial spreads. The radial pattern can be understood viewing the underside of the specimen. The olmiite colour colour is attractive with the hint of strawberry and the crystal surfaces are sprakling lustrous. There are a couple of minor abrasions.
