{"product_id":"amethyst-flower-d-natural-brazil","title":"Amethyst flower (D) — natural, Brazil","description":"\u003cp dir=\"ltr\"\u003eA near-circular formation with flower formations across the top and good depth of purple.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe colour is iron, but not in the ordinary way. Most mineral colour comes from a metal simply being present. Amethyst needs two things: iron caught in the quartz structure as it grew, and then natural radiation from the surrounding rock working on that iron over a very long period. Take away either and the quartz comes out clear.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSo the purple is a record of where the crystal sat and what was around it, not just what it was made of. Two geodes from the same flow can come out completely different depths of colour.\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 11 x 10 x 12.5 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.115 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":58641987993944,"sku":null,"price":140.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/afb-d-1.jpg?v=1791108929","url":"https:\/\/thecrystalshowroom.com\/products\/amethyst-flower-d-natural-brazil","provider":"The Crystal Showroom","version":"1.0","type":"link"}
