Black Tourmaline Collection

Black Tourmaline is the gemstone which protects you from bad omen and also reversed any magic.

Egyptians believed that Tourmaline came to Earth from the core of the earth, after passing over the entire sky on a rainbow-lit day and turned into the celestial gemstone that it is now. To the aborigines and shamans of the west, tourmaline protected the wearer from all evil while Indians believed that Tourmaline brought direction and destiny closer to present tense.

The secret behind the energy of Tourmaline is its reaction to far infrared rays that penetrate the human body and changes its energy flow. Tourmaline is sourced from the Sinhalese word thuramali, meaning- something small from earth.
