Uvarovite is named after Count S. S. Uvarov, (1765-1855), president of the St. Petersburg Academy and mineral collector.

This is the rarest of the garnet family. Colored by chromium, it is always a dark, rich green. The crystals are small and most people have only seen examples of druzy on matrix.

Faceted uvarovites are extremely rare because crystals are always opaque. An occasional crystal may have a transparent corner that could yield a stone of less than 1 carat, even though crystals may reach a size of 1-2 inches.

The crystals are usually opaque. Only small corners of larger crystals have the transparency for faceting. Anything over one carat is exceptionally rare for a faceted uvarovite. Collectors are grateful to have a faceted uvarovite of any size. They are so rare; there simply are not enough to go around.

The color of uvarovite is like that of emerald (deep, rich green), so it is a shame that crystals cannot be cut. Uvarovite is a rare mineral, prized by collectors. It is not generally regarded as a gem garnet.

OPTICS: N= 1.74-1.87.
