WebCerussite is a mineral composed of lead carbonate with a hardness of 3.5. It has an orthorhombic crystal system. The Czech Republic, Sardinia, Austria, Scotland, Namibia, and the United States all produce high-quality specimens of this crystal. It must be handled with care because of its fragile nature to prevent injury. WebCerussite occurs in metalliferous veins in association with galena, and has been formed by the action of carbonated waters on the galena; it is therefore found in the upper parts of …

This reaction began with the growth of a cerussite shell on top of calcite surfaces followed by the replacement of the remaining calcite core.
Cerussite (also known as lead carbonate or white lead ore) is a mineral consisting of lead carbonate (PbCO3), and is an important ore of lead. The name is from the Latin cerussa, white lead.
