- N'Chwaning Mine, Kalahari Manganese Fields, South Africa
- Cabinet, 10.2 x 5.5 x 2.2 cm
A rich vertical plate just covered with gemmy, sparkling poldervaartite crystals to over 1 cm! This piece gives you a lot of visual area for the money, and large specimens in this quality were never common even when found. Note the presence of both crystal forms, elongate crystals and spherical aggregates.
