Tourmaline is the October birthstone and gemstone for the 8th wedding anniversary. Tourmalines have a highly variable chemical composition and contain more than a dozen mineral species in their group. Their very complex chemical composition gives rise to a wide range of colors including green verdelite, blue indicolite, and red rubelite. With the widest color ranges of any gem species, Tourmalines occur in many shades of virtually every hue, with some Tourmalines even displaying multiple colors. Tourmalines also present intriguing optical effects including pleochroism, which is when the stone changes color as it is rotated, and chatoyance, or a "cat's eye" seen in reflected light. Crystal healers believe Tourmalines help with detoxification, support fat loss, improve circulation, improve the mood, eliminate toxic metals, reduce water retention, support the liver and kidneys, and reduce lactic acid. According to ancient legend, Tourmaline comes in a wide variety of hues because it traveled along a rainbow and gathered all the rainbow's colors. Thought to boost creativity, Tourmalines are used extensively by writers and artists. Interestingly, Tourmalines are pyroelectric, meaning that the stones become electrically charged when heated. They are also piezoelectric, which means that they become electrically charged when squeezed. A 7 to 7.5 on the Mohs hardness scale, Tourmalines are perfect for use as center stones in rings, earrings, and pendants. A highly valuable and desired gemstone in the jewelry marketplace, Tourmalines are thought to strengthen the mind and spirit.
