Beskrivning:
Gartrellite, Olivenite
- Locality: Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia (Locality at mindat.org)
- Size: 2.9 x 1.9 x 1.9 cm.
- Found in December of 1974, this is a FINE olivenite on its own merit. The piece features a nearly gemmy crystal with great lustre, measuring almost 1 cm tall, and perched beautifully! However, the greater rarity lies in those sparkling sub-mm microcrystals at the base of the olivenite cluster. This is an extremely rich occurrence of GARTRELLITE, which is the much rarer species by far. This has been confirmed by SEM and EDS, by the way; though the association is also indicative of gartrellite at Tsumeb. Ex. Ulrich Baumann Collection.
