Calcite

Blade-like flattened rhombohedral crystals with a highly lustrous surface and a gentle yellow coloration, likely from trace amounts of iron. Daye County is home to a rich mining history dating back more than 3000 years, focused around the ancient bronze history and evolving into dozens of mines. The mineralization deposits are often in variously copper and iron rich skarns with porphyry, especially modernly, and have produced some of the finest Calcite the world has ever seen.
