Uvarovite: Background and Summary
Uvarovite is a rare mineral that belongs to the garnet family. It is a chromium-rich garnet that has a bright green color. Uvarovite is named after Russian mineralogist Sergei Uvarov, who discovered the mineral in 1832. It is found in metamorphic rocks, often associated with serpentine and other chromium minerals.Uvarovite is easily identified by its bright green color and its crystal structure, which is usually in the form of small, rounded grains. It is also one of the few minerals that is transparent to translucent. Uvarovite is quite hard, with a Mohs hardness of 6.5-7.5, making it a durable gemstone.
Uvarovite is not commonly used as a gemstone due to its rarity. However, it is sometimes used as a minor source of chromium for industrial purposes, as well as in small amounts for jewelry. Uvarovite is also used in some scientific research, particularly in geology and mineralogy.
