Garnet sand is an abrasive with high hardness and chemical stability, obtained from almandine-based garnet, a natural silicate mineral. It stands out as an environmentally friendly and effective alternative in industrial applications such as blasting and waterjet cutting. Because it contains no silica and generates little dust, it is also preferred from an occupational health standpoint.
