Description

A striking mineral combination from the Trepča mining district, Kosovo. The matrix is dominated by bright, golden pyrite crystals, which have replaced earlier pyrrhotite. This pseudomorphic replacement is characteristic for material from this famous ore deposit.

Prominently positioned on top sits a beautifully developed bornonite crystal measuring approximately 25 mm in diameter. The crystal shows sharply defined edges and a bright metallic luster, making it the clear centerpiece of the specimen.

The assemblage is further complemented by white calcite crystals around and near the bornonite, as well as quartz crystals at the base of the piece. Small areas of sphalerite are also present within the matrix. The combination of these minerals creates a highly aesthetic specimen with a very bright and sparkling overall appearance, typical for the famous Trepča mineralization.
