These are coarse grained igneous rocks that form during the final stages of magma crystallization allowing large well formed crystals to develop.\u003cbr\u003eMetamorphic rocks: it can also form in metamorphic environments such as schists and marble, that have been altered by boron rich hydrothermal waters or metasomatism.\u003c\/p\u003e\n\u003cp\u003eHow the combination forms-\u003cbr\u003eGreen tourmaline crystals become trapped as inclusions inside quartz when boron rich silica heavy hydrothermal fluids and mineral solutions infiltrate cavities or fractures during the quartz growth process. The tourmaline nucleates and crystallizes inside or alongside the forming quartz crystal matrix.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":58186583671171,"sku":null,"price":25.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-8400.heic?v=1780592549","url":"https:\/\/crystalandfossils.co.uk\/products\/green-tourmaline-in-quartz-3","provider":"Crystal and fossils","version":"1.0","type":"link"}
