This miniature-sized Willemite presents the classic pale blue-grey botryoidal form known from Tsumeb mine. Compared with Smithsonite the zinc-bearing species Willemite is very rare at Tsumeb. This lovely piece features globular/botryoidal Willemite crystals to 9 mm in diameter with the typical 'frosted' lustre. Associated with these is a fine dusting of murky-green Duftite microcrystals. A fine Tsumeb miniature of this rarity. Ex Weyand collection.

Willemite
Regional guide
Willemite from Tsumeb, Namibia
Tsumeb willemite is the zinc silicate for collectors who usually think of willemite as a fluorescent-mineral classic from Franklin, New Jersey, and then discover that Tsumeb rewrote the aesthetic rules. Here, Zn2SiO4 appears not as massive ore but as glassy to sparkling crystal groups, botryoidal crusts, radiating sprays, delicate acicular “lawns,” and rare individual hexagonal prisms. The colors are equally un-Franklin-like: white, gray, yellow, green, blue-green, turquoise-blue, pale blue, reddish brown, and the much-loved champagne to honey tones. The best pieces have a crisp, jewel-like presence in daylight, often on white calcite or dolomite, with the color contrast that Tsumeb collectors prize.
