Green Tourmaline is one of the premier stones for self-healing. It centers the energies at the heart chakra and it is more conected to the denser vibrations of physical life than is its heart-oriented cousin, Pink Tourmaling. The physical heart in humans is a powerful generator of bio-electricity, creating a measurable energy field that extends twelve to fifteen feet around the body. Green Tourmaline emanates a subtle energy field that can harmonize with that of the heart, engendering wholeness, dynamic balance and stability.
