Quality badge

Consistent quality

Our high standards in processing and quality control ensures each batch contains consistently sized grains of the highest quality almandine garnet. A bag of GMA Garnet™ contains as much as 98% pure garnet. Uncontaminated garnet enables faster cutting and cleaner cuts.


Superior performance

GMA’s waterjet abrasives’ unique grain hardness, density, and toughness ensure the highest production rates and the perfect edge quality with the first cut. Our waterjet garnet can cut virtually any material with a thickness of up to 24 inches.


No oversized grains

GMA Garnet™ has no dust particles or fine grains that hinder garnet flow or oversized grains that block focusing tubes. This means you can count on uninterrupted, efficient cutting from your equipment.


Reduced abrasive consumption

Our unique garnet provides the perfect balance between cutting speed and edge quality, requiring less garnet to make the cut while achieving the best edge quality. This results in direct cost savings and a longer operating life for your waterjet equipment.


Disposal and recycling

GMA has invested heavily in innovative ways to reduce landfill and reprocess garnet, with an expanding number of reprocessing facilities opening around the world.
