Cerussite crystal beds, a well sought after mineral specimen due to the clean, clear crystals and their rarity. The crystals typically have an orthorhombic habit and is found along side the cockscomb mass variation of baryte,making for a dense specimens. We have various sizes in stock and specimens come from Mibladen, Morocco.
Cerussite is a lead carbonate mineral and lead ore, the name was derived from the word 'cerussa', Latin, which was used by miners' during the 1800's and means lead-spar or white lead ore, an allusion to its dense weight and white colouration. Under good conditions, cerussite will often form good orthorhombic crystals, similar to that of aragonite. It typically has a conchoidal fracture and is 3 to 3.75 on the Moh's scale,meaning it is quite soft and can even be scratch with a penny. Our cerussite mineral specimens comprise clear, short orthorhombic crystals and are often found on beds with cockscomb baryte, a common accessory mineral. Today, cerussite no longer has any major industrial use, because of its lead contents, which is deemed poisonous in many countries, it has been phased out, it was as the key ingredient in lead based paints as well as a major constituent in cosmetic products through out history, but in many western countries, this practice has now ceased. These examples are from Mibladen, Morocco & are are available in 1.5" x 1.5", 2" x 2", 3" x 2", 3" x 3", 4" x 3" sizes which will be supplied in a labelled card tray.
