“3.3 x 3.0 x 2.5 cm. Calcite from the Novotroitskiy Quarry of the Ukraine is rarely available. A highly gemmy and lustrous, vivid, golden-amber, triangular calcite rhomb has two calcite "wings". These lighter colored calcite crystals are twinned. Highly unusual, ghostly yellowish-white fluorescence. Accompanied by a Rocksmiths label.
