Added to the collection in 2003.

The tourmaline family consists of at least 14 distinct minerals, but only one, elbaite, accounts for nearly all of the tourmaline gemstones. Tourmaline gems form in a wide range of colors. Although best known in shades of green and red, elbaite can also be blue, purple, yellow, or colorless. Tourmaline can also show several colors in a single crystal, making it possible to cut unique multicolored gems. A suite of 55 tourmaline gemstones, a group pictured here, exhibit a wide range of colors. These tourmaline gems spectacularly demonstrate the range of colors produced from a single mining region in Nigeria and greatly enhance the National Gem Collection.
