Tourmaline is pyroelectric and piezoelectric, meaning it genuinely does build a small electrical charge when heated or squeezed. That is measurable physics, and it is the reason the stone picked up its reputation for moving energy in the first place. It is the shielding stone. Practitioners keep it at doorways, at windows, and at the corners of a room to hold a boundary, and carry a piece when they are going somewhere that takes something out of them. Raw is the usual choice here rather than tumbled. The rough form has more surface and most people find it does the job better, though that is preference rather than mineralogy. Practical Ways to Use Set a piece at each corner of a room, or one at the front door. Keep one by a router, a desk or a bed if screens are part of the problem. Carry a piece to work that drains you, and rinse it clean when you get home. Natural stone. Size and shape vary from piece to piece. Why We Carry It The shielding stone, unpolished.
