Product Details

A classic Mexican sulfide–gangue association from the Cozamin Mine featuring iron‑rich goethite and lustrous calcite encrusting or perched on a clear to milky quartz matrix. The goethite shows earthy to metallic, dark brownish botryoidal or crystalline masses, contrasting with the calcite’s creamy luster and the underlying quartz’s glassy transparency. This combination reflects supergene oxidation and hydrothermal vein processes typical of the Cozamin vein system. Locality – Cozamin Mine, Zacatecas City, Zacatecas, Mexico Weight - 9.1 OZ Approx.
