Tourmaline is used as a gemstone, occuring in all colors. Dravite merely means brown. Tourmaline also has many scientific and technological uses due to the fact that an electrical charge can be induced in some tourmaline crystals simply by applying pressure to the crystal in the direction of the vertical crystal axis. This effect is known as piezoelectricity, and has many uses in pressure measuring equipment and other scientific applications. Some tourmalines also show pyroelectricity, which occurs when the crystal is heated yielding a positive charge at one end of the crystal and a negative charge at the other.
Tourmaline is the birthstone for the month of October.
