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 ...
Spessartine forms a solid solution series with the garnet species almandine. [4] [5] Well-formed crystals from this series, varying in color from very dark-red to bright yellow-orange, were found in Latinka, Rhodope Mountains, Kardzhali Province, Bulgaria. [12] Spessartine, like the other garnets, always occurs as a blend with other species.

[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 ...
While market saturation was one reason for the fall in YAG production levels, another was the recent introduction of the other artificial garnet important as a diamond simulant, gadolinium gallium garnet (GGG; Gd 3 Ga 5 O 12). Produced in much the same manner as YAG (but with a lower melting point of 1750 °C), GGG had an RI (1.97) close to ...
