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 ...
