Natural Black Tourmalines and Tourmaline Ceramic Micro Spheres are famous for their ability to produce anions naturally. They help create a relaxing environment great for all-night peaceful sleeping as other crystals Tourmalines produce radiant rays. Both energies increase when more heat is applied.

Tourmaline crystals are piezoelectric and pyroelectric.

  • Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals, certain ceramics, and biological matter in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure. The piezoelectric effect is generally thought to act as a force sensor. This effect was exploited by research conducted at the University of Pennsylvania in the late 1970s and early 1980s, exploring the sustained application of electrical potential.
  • Pyroelectricity is the ability of Tourmaline gems to generate a temporary voltage when they are heated or cooled. The change in temperature modifies the positions of the atoms slightly within the crystal structure, such that the polarization of the material changes. This polarization change gives rise to a voltage across the crystal. It is believed to be highly beneficial.

So when Tourmaline stones are pressed or heated, they produce an electrical potential and negative ions that have been linked with happiness, optimism, and energy.

All these properties make Tourmaline one of the most important stones.

Ereada® Gemstone mats, in addition to special anion layers inside, may be filled with Natural Black or BrownTourmaline 3-10mm Tumbled Gems or Ceramic Balls for negative ion emission.

Tourmaline stones naturally emit Negative ions up to 1000-1500 ions per cubic centimeter of the air, creating a refreshing and revitalizing environment in the area where the Ereada® Mat is used.
