tourmaline
October birthstone mineral
Tourmaline is a crystalline mineral prized as a gemstone, occurring in a remarkable range of colors—black, pink, green, blue, and multicolored varieties that shift from one hue to another within a single crystal.
The stone is used in jewelry and, because of its electrical properties, in some industrial applications.
She wore a ring set with pink tourmaline.
