米国のGMA生産 (GMA USA)

米国のGMA生産 (GMA USA)
Our high-quality crushed garnet is mined and produced from our hard rock garnet mine in USA. 

The garnet deposits from Alder, Montana, were formed by a unique history of erosion and deposition, resulting in the toughest grains, optimally shaped for abrasive applications.

All internationally sourced garnet is processed into the highest quality abrasives at our processing plants located throughout the USA.
