It is a variety of calcite where a portion of the calcium ions is substituted by cobalt, and yielding the characteristic pink or purple-pink hue.\u003cbr\u003eCrystal system: Hexagonal (trigonal) crystal system. It frequently display’s rhombohedral or scalenohedral crystal habits,often forming as sparking druzy crusts or rounded Botryoidal clusters over a matrix.\u003cbr\u003eRock formation: It typically precipitates at a relatively low temperatures in oxidizing environments where cobalt rich nickel zinc or copper bearing hydrothermal fluids percolate through host rocks. It is frequently found in mineral veins or as a secondary coating on matrix rocks like limonite or iron oxides. \u003cbr\u003eHardness: measures 3 on the MOHs scale.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":58365614588291,"sku":null,"price":30.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-9258.heic?v=1782838967","url":"https:\/\/crystalandfossils.co.uk\/products\/cobaltoan-calcite-2","provider":"Crystal and fossils","version":"1.0","type":"link"}
