Tourmaline comes from toramalli, which means “mixed gems” in Sinhalese (a language of Sri Lanka). It’s a term Dutch merchants applied to the multicolored, water-worn pebbles that miners found in the gem gravels of Ceylon (now Sri Lanka).

Many tourmaline color varieties have inspired their own trade names:

  • Rubellite is a name for pink, red, purplish red, orangy red, or brownish red tourmaline, although some in the trade argue that the term shouldn’t apply to pink tourmaline.
  • Indicolite is dark violetish blue, blue, or greenish blue tourmaline.
  • Paraíba is an intense violetish blue, greenish blue, or blue tourmaline from the state of Paraíba, Brazil.
  • Chrome tourmaline is intense green. In spite of its name, it’s colored mostly by vanadium, the same element that colors many Brazilian and African emeralds.
  • Parti-colored tourmaline displays more than one color. One of the most common combinations is green and pink, but many others are possible.
  • Watermelon tourmaline is pink in the center and green around the outside. Crystals of this material are typically cut in slices to display this special arrangement.
