Gems and crystals have properties that act on our senses because they are made up of minerals that are identical to the minerals in our bodies. Scientists have shown that crystals and minerals exist in our bodies.

1) Lithotherapy acts by the colors emitted, colored vibrational waves. The energy of the color has a strong action on our senses, and on physiological functions.

2) Lithotherapy acts by enzyme reactions: gems in contact with the skin transmit their properties through enzyme reactions. They diffuse infinitely small doses of minerals, copper, lithium, silicon, etc. (like the principle of homeopathy).

3) Lithotherapy acts by piezo-electricity: a quartz necklace creates a frequency phenomenon around the neck that regulates nerve influxes, removing stress and inflammation problems.
