Willemite - Tsumeb

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.
