Tourmaline is available in more colors than any other gemstone, so it is fitting that it serves as the birthstone for October, when the seasons change in the Northern hemisphere and trees are alive with color. The ancient Egyptians attributed this profusion of colors to the tourmaline’s long journey up from the center of the earth, during which it passed over a rainbow. We have varieties of tourmaline gemstones which are elbaite, liddicoatite, dravite, uvite, and schorl.
