How is GMA GARNET different from other garnet material?
GMA’s garnet is mined from an ancient beach sand deposit. The individual grains have been eroded from the mountainous interior of Australia and transported by fast moving streams and rivers to their present resting place. Centuries of wave action reduced the grains to an ideal size for most blasting and other abrasive applications. No crushing, which tends to weaken the grains and to leave unwanted sharp edges, is used in the production of GMA garnet products. Each grain is 100% natural.
