- Chalcocite (rare for locality!)

- Ex. Shields & Frances Flynn
A rarity for Tsumeb, and highly sought after as a species in general, these well-developed Chalcocites occupy two vugs within a microcrystalline sulphide matrix. The complex and lustrous crystals reach up to 1.2 cm, and they have excellent striations along the sharp faces. A number even have a lovely, blue, iridescent patina, which is a highly-desired characteristic of Chalcocite. Overall, this is an abundant and representative Chalcocite specimen for this important locality.
