Are Ereada® mats built only with amethyst and not with tourmaline?

Amethyst is considered the primary stone, which is why it is mainly used in our mats. It is the only stone used in the Purple Ereada® mats and the Brown Ereada® mats collections.

We also offer another collection that includes four natural gemstones along with four types of tourmaline ceramic microspheres designed to enhance ion production. These are the Ereada® Gemstone mats.

Ereada® Gemstone mats still contain a large amount of amethyst, making up nearly half of the stones used. The remaining gemstones include agate, green chalcedony, and garnet. Some customers prefer having a variety of stones, which is why this collection is available.

If you are particularly interested in tourmaline, Ereada® Gemstone mats are a good option. Every second crystal tube contains a blend of four tourmaline ceramic balls.

The Negative Potential (N.P.) function, also known as E.D.N.I. (Electrical Discharge of Negative Ions), was first integrated into the Mini Ereada® Gemstone mats. Previously, EDNI/NP was available only in Compact Pro and larger Ereada® Brown mats and in Professional or larger Richway Bio-Mats.

We now also offer Brown Mini mats with the N.P. function.

The PEMF (Pulsed Electromagnetic Field) function is available in Compact Pro and larger Ereada® Gemstone mats. These models also include twelve static magnets with a strength of 300 gauss. This makes the Gemstone collection a good choice for customers who want a mat with tourmaline and advanced features manufactured in Korea.
