Tourmalines are useful for any sort of emotional healing practices, whether they are directed by you, at you, or both. I enjoy using pink and green tourmalines to form loving connections with plants. Tourmaline can be used to remove energy blockages, especially at the heart, and can also be used to untangle emotional hang-ups and examine thought processes in a productive but gentle, loving way. Tourmaline crystals are also pyro- and piezoelectric, meaning that they develop a small electric charge when heated or compressed.
