While it is famous for its metallic silver to earthy red appearance,its technical specifications depend heavily on its crystal structure and chemical makeup.\u003c\/p\u003e\n\u003cp\u003eCrystal system- Trigonal. When it grows in platy or micaceous habits-featuring flat flake like,or scale like layers it is frequently referred to as specular hematite or specilarite.\u003cbr\u003eMineral class- Oxides\u003cbr\u003eHardness- 5.5-6.5 on the MOHs scale.\u003cbr\u003eWhile it is harder then pure iron,its structure makes it quite brittle,and its apparent hardness can drop down to 5 in its softer earthier forms.\u003cbr\u003eRock formation- Hematite is a highly versatile rock forming mineral that develops in all three major geological environments.\u003cbr\u003eSedimentary rocks- This is the most abundant source. It precipitates directly out of iron-rich marine or lake waters,acting as a natural cement. \u003cbr\u003eMetamorphic rocks- It forms as a result of intense heat and pressure,often during contact metasomatism where hot,chemically active fluids alter surrounding rocks into high grade ore bodies. Platy or crystalline varieties frequently develop in metamorphic fractures and hydrothermal veins as hot fluids cool down.\u003cbr\u003eIgneous rocks- It occurs as an accessory mineral in volcanic environments,occasionally forming via volcanic sublimates (gases cooling directly into crystals) or as minor inclusions in magmatic rocks.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":62972244459907,"sku":null,"price":40.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-1706.heic?v=1792680590","url":"https:\/\/crystalandfossils.co.uk\/products\/hematite-platy","provider":"Crystal and fossils","version":"1.0","type":"link"}
