A STRIKING, OLD-TIME and RARE specimen from the famous Czar Shaft at Bisbee. Gorgeous and lustrous, bright red, calcite crystals are included with cuprite variety chalcotrichite and copper in numerous, very well-placed vugs on BOTH SIDES of the robust gossan matrix. The calcite crystals are found in clusters or as beautiful, isolated crystals to 6-7 mm or so. Fabulous, desirable Bisbee material found at the 200 ft. level of the Czar Shaft prior to the mine closing in 1944, according to the accompanying dealer label. Ex. Dave & Emily Stoudt Collection.
