Lovely specimen of Dioptase crystals from Tsumeb Mine in Namibia. The Dioptase covers a large part of the stone, but the best crystals are located in a vug that we have photographed under the microscope (photo 3), so you can see the details. There is a price label still on the specimen, you will receive the stone with a label from the 70`s, typed on one side and handwritten on the other. The specimen comes from an old German collection.
Please note that the crystals are very small and it is advised to view them under magnification. The specimen in total measures up to 4.2cm/1.65inch, the vug with crystals is approx. 1cm/0.39inch. Weight:67g.
