A very special specimen of Willemite var. Troostite from the Tsumeb Mine. There are larger specimens, but this one has always been my favorite Tsumeb Willemite due to the instantly memorable and totally unique "donut" shape of the piece. The icing on the cake is that the overall quality of the crystals is also as good as one could hope for.

When I first started collecting, I saw a picture of this piece in my Facebook feed and immediately wanted such a memorable piece in my collection. Just two years later, I was lucky enough to acquire this piece.

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.
