This 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. 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. A favorite of yesteryear, this rose-cut faceting features a flat base (no pavilion) and a crown made up of triangular facets.
