Chalcostibite


Chalcostibite is a copper antimony sulfide. Chalcostibite takes its name from its composition, using the Greek roots chalkos, meaning copper, and stibi, antimony. Glocker (1847) assigned the mineral its modern name.

This is an attractive specimen consisting of tight aggregates of iridescent chalcostibite on quartz. The chalcostibite forms crystals to 3 mm in globular aggregates to 1 cm across. While not having the multi-centrimetric crystal size seen from Morocco, this material represents fine unaltered crystals with brilliant metallic luster. Former Robert Noble collection with label.
