Uvarovite

This page is currently not sponsored. Click here to sponsor this page.
Count Sergey Semeonovich Uvarov
Formula:
Ca3Cr2(SiO4)3
System:
Isometric
Colour:
Green, emerald-green, ...
Lustre:
Vitreous
Hardness:
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).

Note: some uvarovites show Al-Cr cation ordering, resulting in orthorhombic, monoclinic or triclinic symmetries (while still being strongly pseudocubic), see articles by Andrut & Wildner (2001, 2002).
