{"product_id":"tanzanite-8-x-6mm-pear-faceted-gemstone-aa-grade","title":"Tanzanite 8 x 6mm Pear Faceted Gemstone, AA-Grade","description":"The blue-violet color of high-quality tanzanite makes it a sought-after gemstone; this AA-grade, pear tanzanite is an ideal choice for colorful, high-end jewelry designs. Mount it in a white-metal setting or in yellow gold—it pairs well with both. Tanzanite is one of the birthstones for December.\n\nTanzanite, a name first used by Tiffany \u0026amp; Co., is a blue\/purple variety of zoisite, which is a trichroic gemstone—it often exhibits different colors when seen from different directions. These gemstones are cut to show the orientation of deep blue to violet-blue colors; the blue color is due to the traces of vanadium in the crystal structure.\n\nThe pear cut is a hybrid of the oval and marquise cuts; it is usually oriented with the point uppermost.\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice Per Unit:\u003c\/strong\u003e Priced per Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGemstone Type:\u003c\/strong\u003e Tanzanite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Shape:\u003c\/strong\u003e Pear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Size:\u003c\/strong\u003e 8 x 6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Type:\u003c\/strong\u003e Natural\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Medium Blue-Violet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBirthstone:\u003c\/strong\u003e December\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhancement:\u003c\/strong\u003e Heat-treated (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMohs Hardness:\u003c\/strong\u003e 6–7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClarity:\u003c\/strong\u003e Eye-clean\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefractive Index:\u003c\/strong\u003e 1.692–1.7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecific Gravity:\u003c\/strong\u003e 3.35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e AGTA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral Source:\u003c\/strong\u003e TANZANIA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.000 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Amadesa","offers":[{"title":"Default Title","offer_id":50754698740058,"sku":"73857","price":37052.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/73857in1.jpg?v=1742359638","url":"https:\/\/www.amadesa.com\/ja-jp\/products\/tanzanite-8-x-6mm-pear-faceted-gemstone-aa-grade","provider":"Amadesa","version":"1.0","type":"link"}
