Elbaite is a colorful member of the tourmaline group of minerals. The name tourmaline comes from the word “turmali,” a Sinhalese term for mixed precious stones. Tourmaline gems cover the complete range of the color spectrum, but in exquisite shades unlike those of any other gem material. Although tourmaline is best known in shades of green and red or pink, it can also be blue, purple, yellow, brown, and colorless. Tourmaline comes in many color-specific varieties, including indicolite (blue), rubellite (red), paraiba (neon blue), watermelon (pink surrounded by green), bi-colored (two colors in one crystal), and multi-colored (three or more colors in one crystal). Today Brazil is the largest producer of gem tourmaline; other important sources include Sri Lanka, Madagascar, Mozambique, Afghanistan, Tanzania, Russia, Malawi, Nigeria, Namibia, Zambia, the U.S. and elsewhere.  High quality tourmaline crystals have been found at the Havey Quarry in Maine. Most are a deep bluish-green color. Faceted by American lapidary artist, Larry Woods, this modified rectangular cut gem weighs 30.62ct and was cut from a crystal that weighed approximately 12.6g. The crystal pictured with the gem is also from the Havey Quarry and a good representation of gem-quality rough. This U.S. gemstone and crystal are a wonderful addition and upgrade for the National Gem Collection. Photos courtesy of Robert Weldon.
