It lines the gas cavities in Brazilian basalt before anything else arrives, and it is the reason so many amethyst geodes from Rio Grande do Sul have a green skin under, over or through the quartz. Botryoidal means it grew in rounded bubble-like masses rather than crystals, which is normal for the way clay minerals build up.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWorth being clear about a term you will see elsewhere. This is not green amethyst. Green amethyst means prasiolite, which is almost always amethyst that has been heated in a kiln to change its colour. Nothing here has been heated. The green is a separate mineral sitting on top of the purple, and the two grew at different times.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eKeep it out of direct sunlight. Sustained UV breaks down the iron centres that produce the purple, and amethyst that fades does not come back.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMineral:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eAmethyst, the purple variety of quartz (SiO₂), with celadonite\u003cbr\u003e\u003cstrong\u003eCrystal system:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eTrigonal\u003cbr\u003e\u003cstrong\u003eOrigin: \u003c\/strong\u003eRio Grande do Sul, Brazil\u003cbr\u003e\u003cstrong\u003eHardness: \u003c\/strong\u003e7 on the Mohs scale; hard, though fine druzy points chip easily\u003cbr\u003e\u003cstrong\u003eTreatment: \u003c\/strong\u003eNone\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 12.63 x 7.2 x 19 cm\u003cbr\u003e\u003cstrong\u003eWeight: \u003c\/strong\u003e1.02 kg                                                                                                                                            \u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eSupplied on a bespoke gold stand\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eYou will receive the exact piece photographed.\u003c\/p\u003e","brand":"The Crystal Showroom","offers":[{"title":"Default Title","offer_id":58546496667992,"sku":null,"price":125.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/afb-b-1-2.jpg?v=1790155967","url":"https:\/\/thecrystalshowroom.com\/products\/amethyst-flower-b-natural-brazil","provider":"The Crystal Showroom","version":"1.0","type":"link"}
