GRS is a company inspired by the love of engraving and established by two innovative men, Don Glaser and John Rohner, and later expanded by Don’s son, D.J. Glaser. That inspiration has since been carried on through creation, innovation, and preservation of the arts of hand engraving and stonesetting.

Through a working relationship with the industry, GRS has been able to meet and exceed the needs of customers since 1977. GRS has become a global brand recognized for its quality, customer service, and inventive solutions.


The GRS Training Center is more than a classroom where innovative techniques are shared. It is the beginning of new friendships, an invigorating setting for artistic achievement, and a significant part of your creative journey.

No other learning experience provides the same opportunity and guidance. For over 20 years, GRS has pioneered and constantly improved this unique training. Each instructor is chosen for their ability to help you learn more in far less time.
