{"product_id":"tanzanite-round-rose-cut-cabochon","title":"Tanzanite Round Rose-Cut Cabochon","description":"\u003cp\u003eThis round, rose-cut tanzanite features an attractive blue and purple trichroism; an ideal choice for one-of-a-kind jewelry designs. Highlight this feature by using it to create a pendant with a single gemstone or combine it with a variety of other gems to create multicolor  necklace and earring designs. 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\nA favorite of yesteryear, this rose-cut faceting features a flat base (no pavilion) and a crown made up of triangular facets.\u003c\/p\u003e","brand":"AGTA","offers":[{"title":"3mm","offer_id":52672046760282,"sku":"78764","price":18.59,"currency_code":"EUR","in_stock":true},{"title":"4mm","offer_id":52672046793050,"sku":"78765","price":40.04,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/78764_050330.jpg?v=1763142759","url":"https:\/\/www.amadesa.com\/nl-nl\/products\/tanzanite-round-rose-cut-cabochon","provider":"Amadesa","version":"1.0","type":"link"}
