{"product_id":"square-faceted-imitation-sapphire-lab-created-blue-spinel","title":"Square Faceted Imitation Sapphire","description":"\u003cp\u003eMimicking the rich royal blue of natural sapphire, these square faceted imitation sapphires are composed of lab-created blue spinel. Offering an affordable alternative to natural corundum, they deliver consistent color and clarity in calibrated sizes suited for a wide range of jewelry applications. These stones are generally safe for stone-in-place casting, though some risk of damage may occur. Clean with warm, soapy water; ultrasonic and steam cleaning are generally safe. Note that calibrated gemstone sizes may vary slightly by +\/– 0.10 mm.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSapphire simulant\u003c\/strong\u003e with rich royal blue color\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposed of synthetic spinel\u003c\/strong\u003e (lab-created blue spinel)\u003c\/li\u003e\n\u003cli\u003eGenerally safe for stone-in-place casting\u003c\/li\u003e\n\u003cli\u003eCompatible with ultrasonic and steam cleaning\u003c\/li\u003e\n\u003cli\u003eCalibrated sizes for consistent fit; may vary by +\/– 0.10 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eStone Type\u003c\/th\u003e\n\u003ctd\u003eImitation Sapphire (Sapphire Simulant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003eLab-Created Blue Spinel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eSquare Faceted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize Tolerance\u003c\/th\u003e\n\u003ctd\u003e+\/– 0.10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCasting\u003c\/th\u003e\n\u003ctd\u003eGenerally safe for stone-in-place casting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCleaning\u003c\/th\u003e\n\u003ctd\u003eWarm soapy water; ultrasonic and steam generally safe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e913-906\u003c\/td\u003e\n\u003ctd\u003e3x3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e913-908\u003c\/td\u003e\n\u003ctd\u003e4x4 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"3x3mm","offer_id":47551816073430,"sku":"913-906","price":2.2,"currency_code":"USD","in_stock":true},{"title":"4x4mm","offer_id":47551816106198,"sku":"913-908","price":4.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/square-faceted-imitation-sapphire-otto-frei.jpg?v=1719954582","url":"https:\/\/www.ottofrei.com\/products\/square-faceted-imitation-sapphire-lab-created-blue-spinel","provider":"Otto Frei","version":"1.0","type":"link"}
