A large piece of black tourmaline in natural form has been cut to size and electroplated on to a bale to magnify the natural beauty of this protection stone.
Since black tourmaline is pleochroic, it might also be green when viewed along a different axis. This crystal 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.
