4551335
location:
Duquesne, Santa Cruz Co., Arizona, USA
description:
Sharp cubic crystals of what were once pyrite measuring to 1.7 cm in size now replaced by goethite and set on a crystalline quartz matrix. This is in very good condition all around. The previous label describes the replacement as hisingerite, I think is goethite.
