Natural calcite crystal specimen featuring well-developed secondary growth apophyllite crystals across the surface, accompanied by visible pyrite aggregates.
The apophyllite crystals display a bright, glassy luster with crisp crystal edges, contrasting beautifully with the underlying calcite structure. Golden metallic pyrite appears in natural pockets beneath the apophyllite layer, adding depth, texture, and visual contrast.
This specimen shows clear multi-stage mineral formation and remains completely natural and unpolished.
Ideal for mineral collectors, display collections, photography, or modern mineral decor.
