Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vibrant emerald-green color, vitreous to adamantine luster, crystal structure is isometric (dodecahedron or trapezohedron), specific gravity is roughly 3.77.
Formation & geological history
Formed in chromium-rich metamorphic environments, commonly associated with serpentinites or skarns where hydrothermal fluids interact with chromite-bearing rocks.
Uses & applications
Primarily used as a rare and sought-after collector's mineral specimen, occasionally cut into small gemstones when crystal druzy allows.
Geological facts
Named after Count Sergei Semenovich Uvarov, a Russian statesman and amateur mineralogist. It is the only consistently green garnet species that is colored by chromium rather than vanadium or iron.
Field identification & locations
Easily identified by its distinctive brilliant green crystal druzy coating on a dark matrix. Notable localities include the Saranovskoye mine in the Ural Mountains of Russia, as well as occurrences in Finland, Turkey, and California, USA.
