This causes the stone to become transparent and almost invisible while in the water. Once it dries out the stone will return back to its opaque state.","brand":"Calder Crystals","offers":[{"title":"Default Title","offer_id":58112904823048,"sku":"CC-EthiopianOpal-Welo-EOS46","price":15.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/6062\/6184\/files\/CC-EthiopianOpal-Welo-EOS46-1_1726042d-0f4d-4138-b68e-07ae5556ca1e.jpg?v=1782809931","url":"https:\/\/caldercrystals.com\/products\/ethiopian-welo-rough-opal-top-grade-specimen-6-6ct-weight-46","provider":"Calder Crystals","version":"1.0","type":"link"}
