System:IsometricColour:Green, emerald-green, ...
Lustre:VitreousHardness:6½ - 7
Name:Named after Count Sergey Semeonovich Uvarov (1786-1855), Russian statesman and scholar, President of the Academy of St Petersburg (1818-1855).


Garnet Group. Grossular-Uvarovite Series.

Uvarovite is the name given to the green calcium chromium garnet end member.
The name has frequently been misused in the past to refer to other green and/or chromium-bearing garnets, many so-called 'Uvarovites' are actually chromian Grossular, chromian Pyrope, green Andradite (the so-called Iranian 'uvarovite') or even the rare Knorringite (magnesium chromium garnet).
