Sea and Rock Garnet

Garnet is a natural and chemically inert mineral, which fractures into angular, sharp, irregular pieces while pressure blasting.
Our garnet, which is mined from hard rock deposits, among the hardest in the world with a Mohs rating between
8.0-8.5.  We also have sea garnet used for blasting and waterjet cutting.
