Calcite & Quartz on Sphalerite

Size: 6.0 x 8.9 x 4.2cm

Weight: 218g 

A nice combo specimen from the Trepca mine in Kosovo. Here is very dark and lustrous sphalerite which has quartz needles growing on one side, and on top of the quartz are larger calcite crystals. The sphalerite crystals are quite large too. 

This specimen comes with a custom Greenstone Mineral Base.
