Tourmaline represents a large group of related mineral species that exhibit many unusual optical and physical properties. Chemically more complex than most minerals, tourmaline exhibits a substantial range of colors and varieties.
This crushed material is a mixture of dark green, light green, pink, blue, black, and yellowish-orange tourmaline. This unique tourmaline mixture would be a great choice for custom and one-of-a-kind art projects. Tourmaline is also one of the official birthstones for October.
Our medium material is considered to be sand sized (very coarse sand to fine sand), ranging between 2 millimeters to 0.25 millimeters. Please see the corresponding sediment size chart.
