- Rosasite on Calcite
- Tsumeb Mine, Otjikoto Region, Namibia
- Miniature, 5.1 x 4.1 x 2.7 cm
- Ex. Shields and Frances Flynn
Rosasite "balls" are one of the more rare colorful copper minerals from the Tsumeb assemblage, especially when seen like this - in isolation, contrasting on a beautiful crystallized white matrix of calcite. Lustrous and translucent, colorless, rhombohedrons of calcite to 1.3 cm across, form the matrix for spherical aggregates of velvety blue-green rosasite, to 1.5 cm across. This is a Tsumeb classic, and an exceptional miniature display specimen. Again, while rosasite itself might be generally obtainable, these isolated spheres are simply not common at all.
