It is entirely unheated and untreated — a distinction that places it in the top fraction of the global Opal supply and is the single most important value driver in the collector market. Australia's Lightning Ridge produces the world's finest black opal — a geological phenomenon so concentrated in optical power that fine specimens rank among the highest per-carat gemstones on the market.\u003c\/p\u003e\n\u003c!--split--\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecies:\u003c\/strong\u003e Natural Opal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.37 cts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 11.78 x 8.60 x 2.01 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape \u0026amp; Cut:\u003c\/strong\u003e Oval, Cabochon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor \u0026amp; Saturation:\u003c\/strong\u003e Gray \/ Light\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClarity \u0026amp; Transparency:\u003c\/strong\u003e N\/A \/ Semi-Translucent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e None \/ Unheated \u0026amp; Untreated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Australia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArchive Reference:\u003c\/strong\u003e OP0061\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eFully Insured Shipping | 30-Day Money-Back Guarantee | GIA, IGI, Other Certification Included (where applicable)\u003c\/em\u003e\u003c\/p\u003e\n\u003cdiv style=\"position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; margin-top: 24px;\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"Skyjems","offers":[{"title":"Default Title","offer_id":45532913664217,"sku":"OP0061","price":1300.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2338\/0931\/files\/OP0061_4_f8391c09-acef-4e08-923a-5a3ce84441ea.jpg?v=1718743323","url":"https:\/\/skyjems.ca\/products\/1-37ct-oval-cabochon-gray-opal-from-australia-op0061","provider":"Skyjems.ca","version":"1.0","type":"link"}
