{"product_id":"polysphaerite-phosphohedyphane-2712-55","title":"POLYSPHAERITE, Phosphohedyphane, Broken Hill, Australia","description":"\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003ePolysphaerite\u003c\/strong\u003e, often referred to as polyspharite, is an outdated term now recognized as a synonym for phosphohedyphane, a mineral that contains calcium, lead, phosphate, and chloride. This mineral is categorized within the apatite supergroup and is commonly found as a calcium-rich variant of pyromorphite. Its chemical formula is Ca₂Pb₃(PO₄)₃Cl, and it typically appears in colors like colorless, white, yellow, grey, or pale green, exhibiting a vitreous to greasy luster. In modern mineralogy, polysphaerite is considered an obsolete term or a specific variant of phosphohedyphane, with detailed information available on platforms like Mindat. Notably, Broken Hill in New South Wales, Australia, is renowned for its exceptional pyromorphite specimens, which include the calcium-bearing variants that polysphaerite represents.\u003cbr\u003e\u003cbr\u003eThe specimen is from around 1980.\u003cbr\u003e\u003cb\u003e\u003cbr\u003ePyromorphite \u003c\/b\u003eis a mineral consisting of lead chlorophosphate, represented by the formula Pb5(PO4)3Cl, and can be found in sufficient quantities to be extracted as a lead ore. It typically forms crystals that exhibit a hexagonal prism shape, often capped with basal planes and occasionally featuring narrow hexagonal pyramid faces. Barrel-shaped crystals are also relatively common, along with globular and reniform aggregates. As a member of the apatite mineral group, pyromorphite closely resembles mimetite (Pb5(AsO4)3Cl) and vanadinite (Pb5(VO4)3Cl) in both physical and chemical properties, making it challenging to differentiate among them without chemical analysis. \u003c\/p\u003e","brand":"Crystals2Collect A.C.N 651.525.727 Pty Ltd","offers":[{"title":"28 25 10 11 \/ Broken Hill New South Wales Australia \/ 2712-55","offer_id":53592965316884,"sku":"2712-55","price":125.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/2047\/9764\/files\/20260805_170615.jpg?v=1785914917","url":"https:\/\/crystals2collect.com\/products\/polysphaerite-phosphohedyphane-2712-55","provider":"Crystals2Collect ","version":"1.0","type":"link"}
