The fluorite is the focal point. The pink colour is concentrated in the centre of each face and fades outward to nearly colourless corners, and the natural triangular growth steps on the octahedral faces are well defined. The crystal is translucent, with a glassy vitreous lustre.\u003c\/p\u003e\u003cp\u003eGalena forms a stepped metallic mass along one side of the fluorite, with bright silver-grey cleavage faces catching the light. A small group of pyrite cubes sits on the back, the striated cube faces and brassy yellow colour clearly visible. A small cream-coloured fibrous mass peeks out at the back edge.\u003c\/p\u003e\u003cp\u003eThe Huanzala Mine in the Huallanca district of Ancash, Peru, produces fluorite, galena and pyrite from hydrothermal lead-zinc-copper veins. The combination of pink octahedral fluorite with stepped cubic galena and striated pyrite is a familiar association from the workings, and a piece of this size brings the three minerals together in one small specimen.\u003c\/p\u003e\u003cp\u003eFluorite is calcium fluoride, CaF2, crystallising in the cubic system with a Mohs hardness of 4 and perfect octahedral cleavage. Pink fluorite is one of the less common colour varieties and is generally attributed to trace yttrium substitution or to colour centres developed by natural irradiation. Galena is lead sulfide, PbS, with a Mohs hardness of 2.5 and perfect cleavage, visible as the right-angle step faces on the metallic mass. Pyrite is iron disulfide, FeS2, Mohs 6 to 6.5, with a brassy metallic lustre on its striated cube faces. The piece should be handled with care because fluorite and galena are both soft and cleave easily.\u003c\/p\u003e\u003cp data-ga-exact=\"1\" style=\"margin:0 0 12px;padding:10px 14px;background:#f6f1e7;border-left:3px solid #c9a84c;border-radius:4px;font-size:0.95em;\"\u003e\u003cstrong\u003eOne of a kind —\u003c\/strong\u003e the specimen pictured is the exact piece you will receive.\u003c\/p\u003e","brand":"Gleamaura","offers":[{"title":"Default Title","offer_id":43627102830798,"sku":"25307","price":1600.0,"currency_code":"MYR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0577\/9714\/8878\/files\/8cd80409d5f55d6f8aaec8bc914edead.jpg?v=1785129937","url":"https:\/\/gleamaura.com\/products\/pink-fluorite-with-galena-and-pyrite","provider":"Gleamaura","version":"1.0","type":"link"}
