Exceptional grouping of transluscent calcite rhombs up to 1.9 cm on edge with inclusions of green duftite. All crystals are sharp with good lustre. A classic specimen from the long closed locality of Tsumeb, Namibia.
Great specimen from Erongo, Namibia. The 1.6 cm sky blue aquamarine displays nicely in against the matrix. Minor schorl crystals are evident at the base.
