Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
A very rich thumbnail specimen of Kegelite, a complex Lead Silicate, from its type location. This is a very rare species consisting of tiny tabular crystals forming a botryoidal crust on matrix. The crystals have a strong pearlescent lustre, and are cream to pinkish in colour. The crust covers an area 18 x 15 mm and appears over 1mm thick in ... |

2.7 x 2.7 x 2.2 cm. This is a fine thumbnail specimen of kegelite. The somewhat gemmy brown-red crystal in the middle is a remarkably sharp and lustrous siderite. It’s a nice accent to the rolling carpet of extremely rich, microcrystalline kegelite. Ex. Walter Kahn and Eric Asselborn Collections.

1.7 x 1.4 x 1.3 cm. Although this may not look like much to most collectors, others will recognize it as an extraordinarily rich specimen of the extremely rare species Kegelite, a lead species found in macrocrystals only at Tsumeb (the type locality). This piece has a rich covering of crystals with characteristic pearlescent sheen to them. The ... |
