Native copper is an elemental metal, while malachite is a vibrant green copper carbonate formed by the weathering and oxidation of copper bearing ores.\u003c\/p\u003e\n\u003cp\u003eNative copper - \u003cbr\u003eCrystal system: isometric (cubic)\u003cbr\u003eMineral class: native elements \u003cbr\u003eHardness:2.5-3 on the MOHs scale\u003cbr\u003eRock formation: native copper forms in two primary geological settings. First, in igneous environments, it precipitates out in the porous amygdaloidal flows of basaltic lava. Second, it can form in sedimentary rocks and the supergene (weathered) zones of sulfide deposits, where groundwater reduces primary copper sulfides into pure metallic copper.\u003c\/p\u003e\n\u003cp\u003eMalachite-\u003c\/p\u003e\n\u003cp\u003eCrystal system: Monoclinic \u003cbr\u003eMineral class: Carbonate \u003cbr\u003eHardness:3.5-4 on the MOHs scale\u003cbr\u003eRock formation: Malachite is a quintessential secondary mineral. It forms in the oxidized (near surface) zones of copper deposits, particularly in carbonate rich host rocks like limestone. When oxygen rich acidic groundwater dissolves primary copper minerals, it reacts with surrounding carbonate minerals(e.g calcite) to precipitate malachite along fractures and cavities.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":58429512253827,"sku":null,"price":8.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/FullSizeRender_a8623dd5-a73f-43c1-9a5a-67016905a60b.heic?v=1783616586","url":"https:\/\/crystalandfossils.co.uk\/products\/native-copper-and-malachite-2","provider":"Crystal and fossils","version":"1.0","type":"link"}
