Calomel is a mercury(I) chloride mineral defined by its chemical composition Hg2Cl2. It forms as colorless to white crystals or granular masses with a vitreous to pearly luster, often presenting a compact habit and occasional tabular or prismatic crystals. Notable specimens hail from classic mercury mining districts in Spain, Germany, the United States, and Serbia, where it has long been associated with high-temperature hydrothermal environments and oxidation zones of mercury-bearing deposits. Collectors value Calomel for its historical significance in mineralogy and its clean, bright appearance in hand samples and cabinets.
