Semi-tumbled black tourmaline with pops of colour from iron.
Due to the complex and various combinations of elements in tourmaline, it is the most multicolored mineral type known, occurring in virtually every color of the spectrum. It has many interesting optical properties. Some specimens appear darker or differ in color when seen through their horizontal versus vertical axis. Certain tourmalines exhibit chattoyancy when polished. This mineral is also piezoelectric which means that through mechanical action an electric pulse is formed, similar to quartz.
Tourmaline is sought after as a talisman of protection to deflect and counteract negative energies. It is also used to guard against radiation and environmental pollutants.
