Agate takes its warm tones from iron oxides carried in by the water that filled the cavity, and the shade depends on how much arrived and what state the iron was in when it did. More oxidised gives redder browns, less gives the yellows and beiges. Each band is a separate delivery with its own chemistry, which is why the colour steps rather than blends.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt is also the honest palette. Grey, white, red and ochre are what untreated Brazilian agate actually looks like, and they are the tones collectors of natural material look for precisely because they cannot be faked convincingly. Dye produces an evenness that the real thing never quite has.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMineral:\u003c\/strong\u003e Agate, banded chalcedony (silicon dioxide, SiO₂)\u003cbr\u003e\u003cstrong\u003eCrystal system: \u003c\/strong\u003eTrigonal\u003cbr\u003e\u003cstrong\u003eOrigin: \u003c\/strong\u003eRio Grande do Sul, Brazil\u003cbr\u003e\u003cstrong\u003eHardness: \u003c\/strong\u003e6\u003cmeta charset=\"utf-8\"\u003e.5 to 7 on the Mohs scale; durable, though the polished face will dull if knocked about\u003cbr\u003e\u003cstrong\u003eTreatment: \u003c\/strong\u003eNone\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 10.35 x 7.2 x 12.8 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 625 g                                                                                                                                          \u003cstrong\u003eNote:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eCut face polished, exterior left natural\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":58512488563032,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/agb-c-1.jpg?v=1789814910","url":"https:\/\/thecrystalshowroom.com\/products\/agate-geode-c-natural-brazil","provider":"The Crystal Showroom","version":"1.0","type":"link"}
