0.7 lbs Calcite and Arsenopyrite 1 Piece Collector Mineral L138
This piece is a specimen of great geological interest, characterized by its association of sulfides and carbonates. The presence of arsenopyrite—the metallic gray component with a well-defined crystalline structure—over a base of white, granular calcite creates a visual contrast that is highly valued in technical collecting.
As the photographs reveal, the arsenopyrite appears in crystal aggregates with an intense metallic luster, appearing to emerge from the calcite matrix. This 347-gram specimen (16 cm x 9 cm x 3 cm) is a perfect example of a hydrothermal formation where the interaction of these minerals has resulted in a balanced and aesthetically attractive piece. It is an essential asset for any collection seeking to represent the diversity of the Ojuela Mine.
