RIVER GARNET SAND
River garnet sand is a type of garnet abrasive that has been deposited into rivers through natural weather processes. While not better than supreme garnet abrasive, river garnet abrasive is cheaper than regular garnet abrasive because it is readily available and is easier to produce. Like sea garnet, river garnet is constantly exposed to natural elements especially flow of river water and therefore has typically smaller mesh sizes and more rounded edges. River garnet also has some impurities but depending on where it is sourced, it may have lower chloride and salt content than sea garnet.
