Silica came out of solution onto the walls of that space and built up in layers, working inwards until the space was full or the water stopped coming.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eCutting and polishing is what makes any of that legible. Sharp band edges mean the chemistry held steady while the layer went down. Blurred ones mean it was changing. A small sugary sparkle in a pocket is the last of the silica finishing as tiny quartz crystals rather than a smooth layer, because there was room left over at the end.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMineral:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eChalcedony (silicon dioxide, SiO₂), banded, so agate\u003cbr\u003e\u003cstrong\u003eCrystal system:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eTrigonal\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eMadagascar\u003cbr\u003e\u003cstrong\u003eHardness:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003e6.5 to 7 on the Mohs scale; durable, though the polished surface will dull if knocked about\u003cbr\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 6.13 x 4.2 x 8.75 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 300 g\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":58430498079064,"sku":null,"price":20.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/oaff-c-1.jpg?v=1788973039","url":"https:\/\/thecrystalshowroom.com\/products\/orca-agate-freeform-c-madagascar","provider":"The Crystal Showroom","version":"1.0","type":"link"}
