Tourmaline - History and IntroductionTourmaline is the gemological namefor an important group of complex gem-quality boron silicate minerals.Tourmaline gemstones can be found in all colors of the rainbow. Owing to itswide range of color availability, tourmaline is considered to be one of today'smost versatile gemstones. Its name is thought to be derived from the Sinhaleseword, "turamali", which means "stone with various colors"in reference to its extreme versatility. Tourmaline was first thought to beused as a gemstone around the 1500s, but distinct mineral species were notactually described until the 1800s. In 1875, George Kunz, an American mineralcollector, introduced green tourmaline from the Mount Mica mine in Maine, USAto Tiffany & Co., which sparked an interest in tourmaline and led to itspopularity (along with other semi-precious gemstones) on the mainstream jewelrymarket. The major tourmaline species includedravite, uvite, schorl, liddicoatite and elbaite. Schorl is the most common variety, making up nearly 95% of all tourmaline deposits, but it is not often desired asa gemstone. Most tourmaline gemstones are varieties of the elbaite family.Since tourmaline consists of a very large group of related gemstones, mosttourmaline is traded under very color-specific varietal names. Some of the morepopular trade names include pink-red 'rubellite', blue-green 'Paraiba', blue'indicolite' and multicolored 'watermelon tourmaline'. Lesser-known trade namesinclude colorless 'achroite', green 'verdelite' and 'chrome tourmaline'. Likesapphire, descriptive names such as 'yellow tourmaline' or 'pink tourmaline'are also commonly used to market fancy-colored tourmaline gemstones. Tourmalinecan occur in a wide range of colors from colorless to black. Colorlesstourmaline is considered to be the rarest, but it is also the least valuabletourmaline. Black tourmaline is actually the most common color occurrence. Mosttourmaline gemstones display two or more colors in a single stone (or two tonesof the same color). Tourmaline crystals that exhibit green on one end and pinkto red on the other, with a band of white in the middle are marketed as'watermelon tourmaline'. Tourmaline exhibits strong pleochroism, which meansits crystals can exhibit different colors depending on the angle from whichthey are viewed. Most red, pink and brown to yellow tourmaline is colored bymanganese, while iron and titanium can result in greenish to bluish-blackcolors. Lithium impurities can result in just about every color, includingblue, green, red, yellow and pink. The rare emerald-green chrome tourmaline iscolored by chromium (and sometimes vanadium). Many pink tourmaline crystalsobtain their color though a natural irradiation process. Cat's eye tourmalineis typically green or pink in color, although it can also occur in other rarercolors too. The most valuable and rare tourmaline is neon green-blue Paraibatourmaline, which is colored by copper. Other valuable color combinationsinclude purplish-red 'rubellite' and blue 'indicolite'. When buying tourmaline, color intensity and saturation are the most important factors.
