Crystal - Polished Quartz, Clear

Crystal - Polished Quartz, Clear is the most powerful healing and energy amplifier on the planet because of its unique helical spiral crystalline form. Found worldwide, it absorbs, stores, releases, and regulates energy and is excellent for unblocking it. When acupuncture needles are coated in Quartz, the effects increase by ten percent. As demonstrated by a Kirlian camera, holding a Quartz crystal in your hand doubles your biomagnetic field. It enhances muscle testing and protects against radiation. Quartz generates electromagnetism and dispels static electricity.
