Large Pyrite (uncommon Mexico locale)

Item Description

A RARE, impressive, large massive compound pyrite crystal specimen from the historic and still active gold, silver and copper mines around the city of Cananea. The dramatic mounded piece is composed of a striking myriad of large and small splendent metallic crystals. The fantastic small stepped-growth crystals in the center are flanked by imposing large well-striated crystals on either side, to 8.5 cm, and the patches of embedded calcite crystals are a fine accessory. This is a remarkable, VERY RARE large pyrite from Cananea. Very hefty at 9.0 pounds or 4.1 kilos mass. A MUST for the species or locality collector! Old material from an old Mexico collection we got into.
