Calcite twin w/ Chalcopyrite (Payne Coll.)

Item Description

An impressive, large blocky calcite rhomb from this famous underground uranium mine, closed since 1982. This striking twinned crystal is translucent and lustrous and is actually near colorless. The rich sprinkling of sparkly chalcopyrite crystals and the grayish iron oxide coating add much pizzazz to this important large example from the Cynthia Payne Calcite Collection. The contact on the front on the upper edge, with trivial brusing and out-of-sight contacting on the back are noted, buy are certainly very modest detractions to this fine calcite.
