{"product_id":"australian-boulder-opal-assorted-bag-3-cunnamulla","title":"Closeout Assorted Bag of 3 Australian Boulder Opals","description":"\u003cp\u003eBoulder Opal is found exclusively in Queensland, Australia, where veins and patches of precious opal form within rugged brown ironstone boulders. These gems were created over millions of years as rainwater dissolved silica from the earth's surface, depositing it into natural cavities within the ironstone. The result is a gemstone of exceptional character — and exceptional durability. The ironstone backing provides natural reinforcement that makes Boulder Opal more resistant to cracks and fractures compared to other opal types. Each assorted bag contains 3 Australian Boulder Opals sourced from rough originated near the city of Cunnamulla, Australia, with at least one stone per bag exhibiting higher opalescence.\u003c\/p\u003e\u003cp\u003eCare instructions: Clean with warm, soapy water only. \u003cstrong\u003eAvoid ultrasonic cleaners, steam cleaners, and any sudden or rapid heat changes.\u003c\/strong\u003e\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEach bag contains 3 Australian Boulder Opals\u003c\/li\u003e\n\u003cli\u003eAt least one opal per bag features higher opalescence\u003c\/li\u003e\n\u003cli\u003eOpaque stones with natural ironstone backing for added durability\u003c\/li\u003e\n\u003cli\u003eShapes include rectangles, rounds, triangles, and free-form\u003c\/li\u003e\n\u003cli\u003eSizes range from approximately 21 x 7 mm (rectangle) to 24 x 24 mm (square)\u003c\/li\u003e\n\u003cli\u003eNo treatments applied\u003c\/li\u003e\n\u003cli\u003eRough originated near Cunnamulla, Queensland, Australia\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eStone Type\u003c\/th\u003e\n\u003ctd\u003eAustralian Boulder Opal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eCunnamulla, Queensland, Australia\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\u003eBacking\u003c\/th\u003e\n\u003ctd\u003eNatural ironstone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShapes\u003c\/th\u003e\n\u003ctd\u003eRectangles, rounds, triangles, free-form\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize Range\u003c\/th\u003e\n\u003ctd\u003e21 x 7 mm – 24 x 24 mm (approximate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003ctd\u003e3 opals per bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThese are natural gemstones; color, pattern, shape, and size will vary from piece to piece.\u003c\/li\u003e\n\u003cli\u003eDo not clean with ultrasonic or steam cleaners.\u003c\/li\u003e\n\u003cli\u003eAvoid sudden or rapid heat changes, which can damage the stone.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":46612265042134,"sku":"990.315","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/990.315NEW_thumb_328c5bf1-0ce6-4fcd-a84d-bec72809881d.jpg?v=1747953900","url":"https:\/\/www.ottofrei.com\/products\/australian-boulder-opal-assorted-bag-3-cunnamulla","provider":"Otto Frei","version":"1.0","type":"link"}
