Tourmaline is a crystalline boron silicate mineral compounded with many natural elements. It is classified as a semiprecious stone and comes in a wide variety of colors, the most spread of which are dark brown and black. The name comes from the Tamil and Sinhalese word "Turmali" which means “a stone from the Earth".

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 biological force sensor. This effect was exploited by research conducted at the University of Pennsylvania in the late 1970s and early 1980s, which established that sustained application of electrical potential could stimulate both resorption and growth (depending on the polarity) of bone invivo.

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 for maintaining cellular potentials on the healthy levels.

So when Tourmaline stones are pressed or heated, they produce an electrical potential and negative ions helping to make us happier, more optimistic, creative and energetic.

Upon heating Tourmaline also emits deep FIR (Far InfraRed) rays. Both effects increase when more heat is applied. The cut and polished surface of the gems can also polarize light by shining rays so enhancing it’s power.

All these properties make Tourmaline one of the most important and powerful stone.

In ancient times brown tourmaline was reputed to be an excellent grounding stone, aligning and protecting the etheric body. It was said to encourage community spirit and social commitment, heal dysfunctional relationships, and increase empathy and feeling of harmony and wellbeing.

While the MediCrystal® Amethyst Mats are supplied with a special layer of nonwoven fabric comprising nano particles of Tourmaline for negative ion emission, the Mixed Crystal Mats use the large and thick 1 to 2 inch diameter disks made of ceramic Tourmaline, which is created by firing and sintering the ultramicro particulate mixture of Tourmaline,Germanium, Elvan and Volcanic rock at 1300° C to remove any impurities.

The Tourmaline stone disks naturally emit healthy Anions (or negative ions) up to 3000 ions per cubic centimeter, creating a refreshing and revitalizing environment in the area where the MediCrystal MatTM is used.
