Apparently derived from the Sinhalese Turamali (1759) referring to mixed-colour gems of unknown identity, this is a stone of variable colour that makes a striking gem when transparent and cut. the pink (rubellite), blue (indicolite) and the more common green are the most popular varieties. Judging from excavations and written descriptions, its diversity of colour made the tourmaline very popular as a precious stone in ancient times. it was valued as a “teller stone” in ancient Eastern Indian culture, providing insight during times of struggle and “telling” who and/or what was the cause of trouble. It has been used by shamans among the African, Native American and Aboriginal tribes and is thought to bring healing powers to the user and to provide protection from danger. Tourmaline can stimulate communication and cooperation between opposing forces and has been used to encourage self-confidence and reduce fear and nervousness by promoting understanding. it is a tranquil, calming stone thought to be good for the lymphatic and digestive systems. Tourmaline is one of the birthstones for October (with opal), signifying hope.
