An outstanding cuprian willemite from the famous Tsumeb Mine in Namibia’s Otjikoto Region! This wonderful, miniature-sized willemite grouping is composed of thousands of minute willemite crystals. The willemite is quite gemmy, highly lustrous, and exhibits the beautiful blue coloration, so sought after by collectors. The blue willemite from Tsumeb is considered, by most collectors, to be the finest in the world. No other locality comes close.
