Tourmaline, a semi-precious gemstone known for its pyroelectric and piezoelectric properties, is gaining traction in both wellness and industrial sectors. In its granular form—such as black tourmaline granules—it is widely used in sweat rooms and saunas, where its ability to emit far-infrared radiation and negative ions is believed to promote detoxification, improve circulation, and enhance relaxation. The raw ore’s natural energy is thought to interact with the body’s biofield, offering therapeutic benefits.
