A fine cabinet specimen of bubbly, botryoidal Willemite from the Tsumeb Mine, Namibia. Translucent pastel duck egg blue to pastel minty green tinted Willemite occurs as hemispherical and near spherical crystals averaging 0.5 to 0.8 cm diameter. To a large extent the Willemite has overgrown a previous deposition of dark green Duftite on and in a reddish Dolomite matrix. Patchy colourless to white crystals of Dolomite have developed in areas on the Willemite. The Willemite has a micro-crystalline sparkling surface and together with the complexity of colour variations makes a remarkably good specimen.

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.
