Hematite

This hematite formed within iron-rich hydrothermal and metamorphic deposits, where iron oxide crystallized into lustrous metallic forms over long periods of geologic activity. The Ouro Preto region of Minas Gerais is world-renowned for its exceptional iron mineralization and historic mining heritage dating back centuries.

Dark, reflective, and often sharply crystalline, this specimen reflects the intense mineral-forming processes that shaped one of Brazil’s most celebrated mineral regions.
