What does cerussite mean?
Cerussite is a mineral composed of lead carbonate (PbCO₃), typically appearing as colourless, white, or greyish crystals with a brilliant adamantine lustre. It usually develops in the oxidized upper zones of lead ore deposits, where carbon dioxide-rich waters alter primary lead minerals such as galena. Cerussite crystallizes in the orthorhombic system and is famous among collectors for its striking twinned forms, including intricate star-shaped and lattice-like aggregates from celebrated localities such as Tsumeb in Namibia and Broken Hill in Australia. Because of its high lead content, the mineral is remarkably dense for its size, and it has long been valued as a significant ore of lead. The name derives from the Latin cerussa, meaning white lead, reflecting both its typical pale colour and its chemical kinship with that historical pigment.
nounA colourless or white mineral consisting of lead carbonate (PbCO₃), typically occurring in orthorhombic crystals; it is an important ore of lead and forms as a secondary mineral in the oxidized zones of lead deposits.
- The mineral lead carbonate (PbCO₃), occurring as colourless to white orthorhombic crystals and serving as an important ore of lead.
"The museum's mineral gallery featured a striking cluster of cerussite crystals from the Broken Hill deposit in Australia."
"Collectors prize the reticulated twins of cerussite found at Tsumeb in Namibia."
"Because cerussite is a primary source of lead carbonate, it was mined extensively alongside galena at Broken Hill."
The plural refers to multiple individual specimens or occurrences of the mineral; as a substance name, cerussite is often treated as uncountable when discussing the material generally.
"The drawer contained several fine cerussites from North African localities."
Named for 'white lead', cerussite can form dazzling star-like crystal twins — yet it's so heavy with lead that a palm-sized specimen feels startlingly dense.

Etymology of cerussite
The name cerussite derives from the Latin cerussa, meaning 'white lead', a term applied to the basic lead carbonate pigment used since antiquity in paints and cosmetics. The suffix -ite follows the standard convention for naming minerals. German mineralogists coined the term in the mid-nineteenth century, drawing directly on the classical Latin root, which also survives in English in the related word ceruse.
How cerussite is actually used
A technical term used almost exclusively in mineralogy, geology, and collecting contexts; it is rarely encountered in general conversation. The word takes no figurative or extended senses.
Easily confused with cerussite
Ceruse is the pigment known as white lead (basic lead carbonate) used historically in paint and cosmetics, while cerussite is the naturally occurring crystalline mineral form of lead carbonate.
