Calcite & Marcasite

A cluster of transparent to translucent calcite crystals with terminations perched on a white matrix, accented by brassy marcasite blades that form intricate metallic clusters. Sourced from the historic Linwood Mine in Iowa, this specimen showcases the striking contrast between the calcite’s bright vitreous luster and the marcasite’s golden sheen and would make an impressive addition to any collection. The matrix on the backside of this specimen does shed a small amount of material, but this does not affect the structure or stability of the specimen.
