Siderite-rich Dolomite forms a rounded platy matrix almost entirely encrusted on all faces with colourless and glassy spherical clusters of Willemite to about 2 mm. From the Tsumeb mine, the Willemite coating is thicker on one side, giving a more creamy appearance. The Willemite fluoresces a dull mustard-yellow in SWUV and pale ghostly-white in LWUV. A great colourless Willemite from Tsumeb in Namibia.

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.
