GARNET SAND
GARNET SAND
Garnet is a semi-precious stone that is derived from mined Almandite and Andradite mineral deposits. After extraction, it is processed and then screened to the grade desired.
At Richa, we've named our minerals RR1- simply because they are the best in the market! We offer our customers three grades of garnet, based on the end user requirements - RR1 Garnet Unwashed, RR1 Garnet Super Washed and RR1 Garnet double washed. The qualities of each grade are outlined in the following table.
