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 particular black tourmaline is from Brazil and has a nice shiny appearance even when crushed. 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.
