Cerussite is a mineral composed of lead carbonate, with the chemical formula PbCO3. It typically forms in oxidized zones of lead ore deposits and can appear in various colors, including colorless, white, or shades of gray. Its crystal structure is often found in prismatic or tabular forms, and it has a high refractive index, giving it a brilliant luster. This mineral is significant in the mining industry, as it can be an important source of lead. Cerussite is also used in jewelry and decorative items due to its attractive appearance. However, it is essential to handle it with care, as lead is toxic.
