Tourmaline exhibits a unique electrical property known as pyroelectricity. This phenomenon occurs when the crystal is heated or cooled, causing it to develop an electrical charge and attract or repel dust particles and other lightweight materials. Similarly, it also exhibits piezoelectricity, where the crystal can become electrically charged under applied mechanical pressure or stress. This property has made tourmaline a subject of interest for scientific study and potential applications in pressure-sensitive devices, but it also adds to the stone’s mystique and appeal in metaphysical circles.
