Tourmaline crystal has obvious thermoelectric effect. When it is heated or cooled, it will generate an equal number of charges with opposite signs along both ends of the tourmaline crystal. At the same time, it has electrostatic dust absorption. This may be due to the expansion or contraction of the crystal and the migration of electric charges excited by the heat in the crystal lattice when the temperature is affected. The tourmaline that reaches the gem level is called tourmaline, which is why the tourmaline on the counter in the shopping mall always falls ash.
