{"product_id":"oval-faceted-imitation-amethyst-spinel-doublet-5x3-12x10mm","title":"Oval Faceted Imitation Amethyst","description":"\u003cp\u003eThis oval faceted imitation amethyst is composed of a lab-created synthetic spinel doublet exhibiting a light to medium purple color. The doublet is constructed from two layers of synthetic spinel bonded together with a tinted adhesive, producing a stone that closely mimics the rich purple hue of natural amethyst — without the characteristic color zoning found in natural gems. Available in eight calibrated oval sizes ranging from 5x3mm to 12x10mm, these stones are well suited for setting in finished jewelry and metalsmithing projects. Calibrated gemstone sizes may vary slightly +\/–0.10mm. Clean with warm, soapy water only; do not apply direct heat.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmethyst simulant\u003c\/strong\u003e with light to medium purple color\u003c\/li\u003e\n\u003cli\u003eComposed of a \u003cstrong\u003esynthetic spinel doublet\u003c\/strong\u003e — two layers bonded with tinted adhesive\u003c\/li\u003e\n\u003cli\u003eMimics the rich purple of amethyst without characteristic color zoning\u003c\/li\u003e\n\u003cli\u003eAvailable in 8 calibrated oval sizes from 5x3mm to 12x10mm\u003c\/li\u003e\n\u003cli\u003eCalibrated sizes may vary slightly +\/–0.10mm\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 Amethyst (Amethyst Simulant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eSynthetic Spinel Doublet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eLight to medium purple\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eOval, Faceted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize Tolerance\u003c\/th\u003e\n\u003ctd\u003e+\/–0.10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCare\u003c\/th\u003e\n\u003ctd\u003eClean with warm, soapy water; avoid direct heat\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\u003e918-212\u003c\/td\u003e\n\u003ctd\u003e5x3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-217\u003c\/td\u003e\n\u003ctd\u003e6x4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-222\u003c\/td\u003e\n\u003ctd\u003e7x5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-228\u003c\/td\u003e\n\u003ctd\u003e8x6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-235\u003c\/td\u003e\n\u003ctd\u003e9x7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-240\u003c\/td\u003e\n\u003ctd\u003e10x8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-244\u003c\/td\u003e\n\u003ctd\u003e11x9mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e918-248\u003c\/td\u003e\n\u003ctd\u003e12x10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThis is an assembled (doublet) stone — avoid ultrasonic cleaners, steam cleaning, and direct heat, as these may affect the adhesive bond between layers.\u003c\/li\u003e\n\u003cli\u003eCalibrated sizes may vary slightly +\/–0.10mm from stated dimensions.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"5x3mm","offer_id":47551824920790,"sku":"918-212","price":5.0,"currency_code":"USD","in_stock":true},{"title":"6x4mm","offer_id":47551824953558,"sku":"918-217","price":8.91,"currency_code":"USD","in_stock":true},{"title":"7x5mm","offer_id":47551824986326,"sku":"918-222","price":9.2,"currency_code":"USD","in_stock":true},{"title":"8x6mm","offer_id":47551825019094,"sku":"918-228","price":11.1,"currency_code":"USD","in_stock":true},{"title":"9x7mm","offer_id":47551825051862,"sku":"918-235","price":12.0,"currency_code":"USD","in_stock":true},{"title":"10x8mm","offer_id":47551825084630,"sku":"918-240","price":22.0,"currency_code":"USD","in_stock":true},{"title":"11x9mm","offer_id":47551825117398,"sku":"918-244","price":23.0,"currency_code":"USD","in_stock":true},{"title":"12x10mm","offer_id":47551825150166,"sku":"918-248","price":28.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/oval-faceted-imitation-amethyst-otto-frei.jpg?v=1719954563","url":"https:\/\/www.ottofrei.com\/products\/oval-faceted-imitation-amethyst-spinel-doublet-5x3-12x10mm","provider":"Otto Frei","version":"1.0","type":"link"}
