Lot 688
Exceptional and Vibrant Dioptase. From Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia - South West Africa.
This specimen is big and showy and makes a bold aesthetic statement. The fabulously rich green color and sparkle on this piece is most outstanding and artistically pleasurable. A few white highlight areas of exposed matrix on the upper back accent the green dioptase.
