Tourmaline



Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors.

Because it contains boron, tourmaline is highly valued throughout known space. In fact, boron is so valued for its uses, that battles from pirate raids to major wars have been fought over it. (See Pleasant Pasture.)
