Tanzanite 9 x 6mm Pear Faceted Gemstone, AA-Grade

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. Tanzanite, a name first used by Tiffany & 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 pear cut is a hybrid of the oval and marquise cuts; it is usually oriented with the point uppermost.
