Description

This AA-grade trillion-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 delicate pendant with a single stone or combine it with a variety of other stones to create multicolor, mixed-stone 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 stones 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.
