{"title":"Cerussite","description":"\u003cp\u003e\u003cstrong\u003eCerussite\u003c\/strong\u003e is a lead carbonate (PbCO3) belonging to the \u003cstrong\u003earagonite group\u003c\/strong\u003e, alongside aragonite, strontianite, and witherite. It forms almost exclusively in the oxidized zone of lead deposits, where carbonated waters attack primary \u003cstrong\u003egalena\u003c\/strong\u003e, making it one of the most important and widespread secondary lead ore minerals. Cerussite crystallizes in striking habits: tabular and pseudo-hexagonal individuals, elongated \"jackstraw\" networks, and above all distinctive twins — V-shaped contact twins and the famous reticulated \"sixling\" star twins prized by collectors. Its high specific gravity, strong adamantine luster, and exceptional dispersion give fine crystals a diamond-like brilliance, though a hardness of only 3–3.5 and perfect cleavage make cut stones extremely fragile and thermally sensitive, so cerussite is collected almost entirely as a display mineral rather than for jewelry.\u003c\/p\u003e","products":[],"url":"https:\/\/www.italmineral.com\/collections\/cerussite.oembed","provider":"ITALMINERAL","version":"1.0","type":"link"}
