Dioptase and Smithsonite on Calcite     Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  A nice showy cabinet specimen measuring 8 x 6 x 3.2 cm.  The bright green dioptase crystal cover much of the display face.  They are small, lustrous, transparent and vibrant.  There is a druse of bright smithsonite crystals in areas. The white spot on the edge is only damaged spot and on first glance really looks like a coating… it is only with magnification that I could tell this was a damaged spot.  $600
