I absolutely love this specimen of dioptase, for several reasons. First, the overall form, the crystals are piled up on two knobs of stark white calcite, so it is much more 3-dimensional than your average specimen. The crystals have the best "Tsumeb-green" color and glassy luster. And the specimen can be displayed from virtually any direction, you can see we have shot it from both sides. Complete save only one damaged little crystal on a side. Really good Tsumeb dioptases are, of course, amongst the most prized specimen in mineral collecting, for their spectacular beauty, and they just get harder and harder to find.
