These gems were created over millions of years as rainwater dissolved silica from the earth's surface and deposited it into natural cavities within the ironstone. The ironstone backing provides natural reinforcement, making Boulder Opal more resistant to cracks and fractures compared to other opal varieties.\u003c\/p\u003e\n\u003cp\u003eThis particular stone is graded \u003cstrong\u003eSome Opalescence\u003c\/strong\u003e, meaning it contains at least a flash of opalescence throughout the stone. The opalescence covers approximately 1–5% of the gemstone's surface and is expressed in primary hues of purple and green. Each stone's pattern is entirely unique and is heightened by the play of opalescence. The rough material originated near the city of Cunnamulla, Queensland, Australia.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSold by the piece.\u003c\/strong\u003e Care instructions: clean with warm, soapy water only. \u003cem\u003eAvoid ultrasonic cleaners, steam cleaners, and sudden rapid heat changes.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExclusively sourced from Queensland, Australia\u003c\/li\u003e\n\u003cli\u003eRough originated near Cunnamulla, Queensland\u003c\/li\u003e\n\u003cli\u003eNatural ironstone backing provides enhanced durability and fracture resistance\u003c\/li\u003e\n\u003cli\u003eGraded Some Opalescence — at least a flash of opalescence visible throughout the stone\u003c\/li\u003e\n\u003cli\u003eOpalescence covers approximately 1–5% of surface area in primary hues of purple and green\u003c\/li\u003e\n\u003cli\u003eEach stone features a unique pattern\u003c\/li\u003e\n\u003cli\u003eOpaque appearance\u003c\/li\u003e\n\u003cli\u003eNo treatments applied\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eOval\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e30mm x 20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStone Type\u003c\/th\u003e\n\u003ctd\u003eBoulder Opal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTransparency\u003c\/th\u003e\n\u003ctd\u003eOpaque\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTreatment\u003c\/th\u003e\n\u003ctd\u003eNone (N)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eQueensland, Australia (near Cunnamulla)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOpalescence Grade\u003c\/th\u003e\n\u003ctd\u003eSome Opalescence (1–5% surface coverage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePrimary Hues\u003c\/th\u003e\n\u003ctd\u003ePurple and green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSold As\u003c\/th\u003e\n\u003ctd\u003eIndividual piece\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eClean with warm, soapy water only.\u003c\/li\u003e\n\u003cli\u003eDo not use ultrasonic cleaners, steam cleaners, or expose to sudden rapid heat changes.\u003c\/li\u003e\n\u003cli\u003eNatural gemstone — pattern and exact opalescence placement will vary per piece.\u003c\/li\u003e\n\u003cli\u003eThis is a closeout item.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":46554651459798,"sku":"990.322","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/990.322NEW1_thumb_84817cde-446d-40c7-b9fb-10e3cdd4404f.jpg?v=1747953978","url":"https:\/\/www.ottofrei.com\/products\/australian-boulder-opal-oval-30x20mm-some-opalescence-cunnamulla","provider":"Otto Frei","version":"1.0","type":"link"}
