Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium. It is classified as a semi-precious stone and the gemstone comes in a wide variety of colors, almost every color of the rainbow. Tourmaline is mined mostly in Brazil and African nations. Tourmalines are believed to be excellent tools for energizing and balancing the chakras.

Tourmaline is used in skin care products because it is an energizing stone that is believed to promote radiant and youthful skin. Rubbing tourmaline crystals on the skin causes them to become positively charged on one end and negatively charged on the other, which creates a warming sensation. According to one manufacturer, this warming effect stimulates the skin to increase the production of new collagen and the contraction of fibers, resulting in a more plump complexion. However, this effect has not been proven in any scientific studies. Tourmaline is primarily used in anti-aging skin care products and exfoliants.
