Crushed Red Jasper (Grade A) from South Africa, Coarse Crush, Gravel Size, 4mm - 2mm

Jasper is composed of micro-crystalline quartz that can come in a variety of different colors and textures. This wide color variation is mainly due to impurities and trace elements within the crystalline lattice. For red jasper, the trace element that gives it its distinct color is iron. This particular red jasper is very high-quality with consistent color and is from South Africa.

Our coarse material is considered to be pea- sized gravel, ranging between 4 millimeters to 2 millimeters. Please see the corresponding sediment size chart.
