description Cerussite Overview
Cerussite is lead carbonate, a mineral formed mainly in the oxidized zones of lead-bearing ore deposits. It crystallizes in the orthorhombic system and commonly appears as colorless, white, gray, or pale-colored crystals; twinned forms are a familiar feature of specimens. With a specific gravity of about 6.5 and high refractive indices, cerussite is valued primarily by mineral collectors, while its lead content requires careful handling.
