From Daye Mine, Hubei, China. This specimen features distinct cubic-form calcite crystals growing on a pyrite-rich matrix. The calcite crystals show clear, blocky geometry with near-cubic outlines and a pale white to light grey tone, displaying a subtle pearly to vitreous luster under light.
Metallic pyrite crystals are visible within the matrix, creating strong contrast between the matte white calcite cubes and the reflective brassy surfaces. The combination highlights both crystallographic form and mineral contrast, making this piece suitable for mineral collections, educational display, or modern shelf presentation.
