{"product_id":"pear-faceted-lab-created-ruby-6x4-10x7mm","title":"Pear Faceted Lab-Created Ruby","description":"\u003cp\u003eCrafted from man-made corundum with the same chemical composition and durability as natural ruby, these pear faceted lab-created rubies offer exceptional clarity with vivid, even coloration. Known as the \"King of Gems\" in Sanskrit, ruby is one of the most desired and valuable gemstones in history, prized since biblical times for its intense red hue.\u003c\/p\u003e\u003cp\u003eRuby is the most valuable variety of corundum and commands the highest per-carat price of any colored stone. Color ranges from orangy red to purplish red, with pure, vivid red to slightly purplish red representing the most prized hues. These lab-created stones display vivid medium to dark purplish red color and are eye-clean. As a synthetic treatment, the lab-creation process itself is the standard used here—no additional heat treatment variables apply.\u003c\/p\u003e\u003cp\u003eThese rubies are safe to fire in metal clay and suitable for stone-in-place casting, making them a practical and beautiful choice for a wide range of jewelry fabrication techniques. Clean with warm, soapy water; ultrasonic and steam cleaning are generally safe.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVivid medium to dark purplish red color, eye-clean\u003c\/li\u003e\n\u003cli\u003eSame chemical composition and durability as natural ruby\u003c\/li\u003e\n\u003cli\u003eMan-made corundum—consistent clarity and coloration\u003c\/li\u003e\n\u003cli\u003eTreatment: Synthetic\u003c\/li\u003e\n\u003cli\u003eSafe to fire in metal clay\u003c\/li\u003e\n\u003cli\u003eSafe for stone-in-place casting\u003c\/li\u003e\n\u003cli\u003eJuly birthstone\u003c\/li\u003e\n\u003cli\u003eClean with warm, soapy water; ultrasonic and steam cleaning generally safe\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\u003eLab-Created Ruby (Synthetic Corundum)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003ePear Faceted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eVivid Medium to Dark Purplish Red\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClarity\u003c\/th\u003e\n\u003ctd\u003eEye-Clean\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTreatment\u003c\/th\u003e\n\u003ctd\u003eSynthetic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBirthstone Month\u003c\/th\u003e\n\u003ctd\u003eJuly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCasting Compatible\u003c\/th\u003e\n\u003ctd\u003eStone-in-place casting safe; metal clay fire safe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\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\u003e919-717\u003c\/td\u003e\n\u003ctd\u003e6x4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e919-727\u003c\/td\u003e\n\u003ctd\u003e8x5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e919-734\u003c\/td\u003e\n\u003ctd\u003e9x6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e919-739\u003c\/td\u003e\n\u003ctd\u003e10x7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"6x4mm","offer_id":47551829246166,"sku":"919-717","price":3.3,"currency_code":"USD","in_stock":true},{"title":"8x5mm","offer_id":47551829278934,"sku":"919-727","price":3.96,"currency_code":"USD","in_stock":true},{"title":"9x6mm","offer_id":47551829311702,"sku":"919-734","price":5.2,"currency_code":"USD","in_stock":false},{"title":"10x7mm","offer_id":47551829344470,"sku":"919-739","price":6.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/pear-faceted-lab-created-ruby-otto-frei.jpg?v=1719954558","url":"https:\/\/www.ottofrei.com\/products\/pear-faceted-lab-created-ruby-6x4-10x7mm","provider":"Otto Frei","version":"1.0","type":"link"}
