Details

Mineral name

Pyrite

Description

This mineral specimen features a dense cluster of interlocking pyrite crystals anchored to a white, crystalline matrix. The pyrite exhibits a brilliant brassy-yellow color with a strong metallic luster. The crystals are well-formed, showing modified cubic and pyritohedral geometries with distinct striations visible on several faces, which is a diagnostic feature of the species. The matrix is composed of small, white, translucent crystals, likely quartz or calcite, which provide a sharp visual contrast to the metallic pyrite. The cluster is three-dimensional, with crystals oriented in various directions, creating a rugged and complex texture. There is no evidence of significant oxidation or tarnish, suggesting the specimen has been well-preserved.
