Uses: Tourmaline works to purify the entire body, including the auric field. It is a wonderful stress reducer, perhaps due to the sheer beauty of the stone. Worn on the person at heart level, Tourmaline conveys peace and tranquillity and helps organize scattered thoughts and emotions.
This stone is also well known for its ability to absorb tremendous amounts of negativity, both from the wearer and from the environment and it can make the wearer more sensitive to the immediate needs of the body-earth.
Black Tourmaline repels rather than absorbs negative energy. This stone is valuable during crises and situations causing emotional stress. It may be used to combat life-threatening diseases as well as to fight pyschic attack, spirit possession and harmful spirit intrusions.
Cat’s Eye Tourmaline should only be used by those who are very attracted to it, as it seems to block energy rather than encourage it.
Clear Tourmaline is like a low-key Quartz. It works to cleanse and detoxify the immune system and may be useful in the treatment of eye problems and biochemical nerve disorders such as epilepsy.
