Mercedes Calcite (Chalcopyrite on Calcite) - Specimen lithium Indonesian Purple Chalcedony is typicallyMined from: Daye Mine, Huangshi, Hubei Province, China Description: This specimen displays the distinctive Mercedes habit of calcite, where multiple tabular crystals intersect at sharp, geometric angles, forming a star like arrangement. The crystals are pale, semi translucent, and well defined, with clean faces that highlight internal growth zoning.
