No flowers on this one.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe brown is iron oxide. Where water moving through the cavity carried iron and left it behind on the crystal surfaces, you get the rust tones, and where it carried iron into the quartz structure instead, you get purple. Same element, two entirely different outcomes depending on whether it ended up on the crystal or in it.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis is the ordinary end of what these cavities produce, and it is worth having for exactly that reason. The showpiece geodes and this piece came out of the same basalt by the same process. The difference is chemistry and luck, not quality.\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 6 x 4 x 10.5 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 100 g                                                                                                                                            \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":58546803409240,"sku":null,"price":20.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/afb-f-1.jpg?v=1790157142","url":"https:\/\/thecrystalshowroom.com\/products\/amethyst-flower-f-natural-brazil","provider":"The Crystal Showroom","version":"1.0","type":"link"}
