Highlight this feature by using it to create a delicate pendant with a single gemstone or combine it with a variety of other gems to create multicolor, mixed-stone necklace and earring designs. Tanzanite is one of the birthstones for December. Tanzanite, 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. The trillion cut features three curved sides, rounded corners and brilliant faceting.\u003c\/p\u003e","brand":"AGTA","offers":[{"title":"5mm","offer_id":50639185969498,"sku":"73407","price":66.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/73407.jpg?v=1741018042","url":"https:\/\/www.amadesa.com\/products\/tanzanite-5mm-trillion-faceted-gemstone-aa-grade","provider":"Amadesa","version":"1.0","type":"link"}
