This specimen features unusually flattened, lustrous and translucent calcites perched on colorless quartz crystals, to 1 cm in length. Associated with the quartz are splendent, brassy yellow crystals of chalcopyrite, to 1 cm across. The disk shaped crystals of lustrous and translucent, white calcite crystals, to 3.25 cm across, are then perched on both the quartz and chalcopyrite. Neat combo specimen!
