Gemmy Cubic Calcite Specimen with Metallic Chalcopyrite Dusting

The specimen displays multiple intergrown cubic calcite crystals, each revealing natural growth zoning and reflective cleavage planes. The calcite ranges from clear to milky white, allowing light to pass through the crystal mass and accentuate internal textures. Tiny chalcopyrite inclusions appear as dark, shimmering specks across select faces and internal planes, adding visual depth without overpowering the crystal structure. This piece makes a striking display specimen for collectors who appreciate classic crystal form combined with subtle mineral contrast.
