Rosasite

This thumbnail specimen from the famous Tsumeb Mine, Namibia features attractive botryoidal clusters of rosasite with their classic soft blue-green tones, nicely contrasting against a bed of translucent, olive-green aggregates that appear to be Olivine (under quick examination). The association is both unusual and visually striking, as rosasite is typically found with carbonates and copper secondaries, while the (possible) olivine adds a distinctive textural and colour contrast not often seen in Tsumeb specimens.

The rounded rosasite botryoids have a silky lustre, even thumbnail-sized pieces like this highlight the diversity and unexpected associations that made the mine a mineralogical legend.
