{"product_id":"quartz-ps-after-calcite-1","title":"QUARTZ ps. after CALCITE","description":"This is a rarely seen example of finely crystallized sugary Quartz replacement (pseudomorphs) after Calcite crystals from the little-known Corona group in the Cababi Mining District, Comobabi Mountains, Pima County, Arizona, USA. This small cabinet-sized piece reveals the typical internal banding, or layering, showing how the replacement progressed in stages. An orange-brown coating across some of the outer surface adds character to this unusual specimen.
