Chalcopyrite on Quartz ps. Calcite

Item Description

A really cool large pseudomorph combination from the famous mines at Concepcion del Oro. Iridescent, lustrous, golden chalcopyrite sphenoids, to 1.1 cm, are dramatically studded on all three sides of the fantastic large calcite scalenohedron pseudomorphed by sugary drusy quartz complemented with a few patches of tiny quartz points. Complete all-around and pristine, this is certainly one of the most unusual and impressive large pseudomorph combinations you will see from this historic locale. RARE and very showy, this old-timer probably dates to the 1960s or 70s or even older. Valued by respected Arizona dealer and collector, Les Presmyk (De Natura) at $1250 on the old dealer label attached.
