Turquoise is heavily used in the traditional jewelry of Native Americans and has been found buried in Ancient Egyptian tombs. Colored by copper — which is responsible for the vivid blues and greens of turquoise — the most prized color has been described as a robin's-egg blue or a pure, vivid sky blue. Some turquoise has matrix present, a spiderweb of veins running through the stone that reveals the surrounding rock present during formation. \u003cstrong\u003eTurquoise is one of the traditional birthstones for December.\u003c\/strong\u003e These oval Sleeping Beauty turquoise cabochons display a high-quality sky blue color with no matrix, making them ideal for clean, classic settings in fine jewelry and traditional Native American-inspired work.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-quality sky blue color with no matrix present\u003c\/li\u003e\n\u003cli\u003eTreatment: Stabilized — resin added to darken and harden the stone\u003c\/li\u003e\n\u003cli\u003eMined in the U.S.A.\u003c\/li\u003e\n\u003cli\u003eTraditional birthstone for December\u003c\/li\u003e\n\u003cli\u003eOval cabochon shape suitable for a wide range of setting styles\u003c\/li\u003e\n\u003cli\u003eAvailable in multiple sizes to suit varied design needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eOval Cabochon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStone Type\u003c\/th\u003e\n\u003ctd\u003eSleeping Beauty Turquoise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eSky Blue, no matrix\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTreatment\u003c\/th\u003e\n\u003ctd\u003eStabilized (resin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eU.S.A.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBirthstone Month\u003c\/th\u003e\n\u003ctd\u003eDecember\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCare\u003c\/th\u003e\n\u003ctd\u003eClean with warm, soapy water; avoid ultrasonic and steam cleaners\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\u003e934-312\u003c\/td\u003e\n\u003ctd\u003e5x3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e934-315\u003c\/td\u003e\n\u003ctd\u003e6x4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e934-317\u003c\/td\u003e\n\u003ctd\u003e7x5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e934-320\u003c\/td\u003e\n\u003ctd\u003e8x6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e934-324\u003c\/td\u003e\n\u003ctd\u003e10x8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e934-327\u003c\/td\u003e\n\u003ctd\u003e14x10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e934-334\u003c\/td\u003e\n\u003ctd\u003e25x18mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"5x3mm","offer_id":47551774752982,"sku":"934-312","price":13.5,"currency_code":"USD","in_stock":true},{"title":"6x4mm","offer_id":47551774785750,"sku":"934-315","price":15.0,"currency_code":"USD","in_stock":true},{"title":"7x5mm","offer_id":47551774818518,"sku":"934-317","price":15.0,"currency_code":"USD","in_stock":false},{"title":"8x6mm","offer_id":47551774851286,"sku":"934-320","price":30.0,"currency_code":"USD","in_stock":false},{"title":"10x8mm","offer_id":47551774884054,"sku":"934-324","price":50.0,"currency_code":"USD","in_stock":false},{"title":"14x10mm","offer_id":47551774916822,"sku":"934-327","price":240.0,"currency_code":"USD","in_stock":false},{"title":"25X18mm","offer_id":47551774949590,"sku":"934-334","price":800.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/oval-sleeping-beauty-turquoise-cabochon-otto-frei.jpg?v=1719954640"},{"product_id":"round-sleeping-beauty-turquoise-cabochon-2-12mm","title":"Round Sleeping Beauty Turquoise Cabochon","description":"\u003cp\u003eTurquoise has been a prized gemstone across many cultures and civilizations, from Ancient Egyptians to Native Americans.

Its enduring popularity stems from its striking chatoyancy — a captivating optical phenomenon in which light reflecting off the stone's fibrous, silky structure produces a shifting, wave-like band resembling an eye. Known traditionally as the \"All-seeing Eye,\" Tiger's Eye displays warm, earthy tones ranging from yellowish-brown and brownish-yellow to reddish-brown. Its durability, affordability, and wide availability make it an excellent choice for everyday jewelry designs.

To be classified as amber, the tree resin must be at least one million years old; otherwise, it is considered Copal, an immature form of amber.
