Most of the garnet at the Tuticorin beach in south India is 80 mesh, and ranges from 56 mesh to 100 mesh size. [citation needed] River garnet is particularly abundant in Australia. The river sand garnet occurs as a placer deposit. [70] Rock garnet is perhaps the garnet type used for the longest period of time. This type of garnet is produced in ...
Gore Mountain Garnet, found in the Adirondack Mountains in New York, contains the world's largest garnets. [1] [2] The rock that holds these garnets, garnet amphibolite, is sometimes referred to as 'black ore' or 'dark ore.' [1] [3] This rock formation formed during metamorphism during the Ottawan phase of the Grenvillian orogeny, and extremely high temperatures combined with introduction of ...

Uvarovite is a chromium-bearing garnet group species with the formula: Ca 3 Cr 2 (Si O 4) 3.
