Most of the garnet at the Tuticorin beach in south India is 80 mesh, and ranges from 56 mesh to 100 mesh size. "River garnet" is particularly abundant in Australia. The river sand garnet occurs as a placer deposit. "Rock garnet" is perhaps the garnet type used for the longest period of time. This type of garnet is produced in
