Tourmaline is a family of gemstones that has been enjoyed by people for centuries. Tourmaline had often been commonly mistaken for other gemstones including ruby, sapphire, and emerald depending on its color. The confusion about this stones identity is even reflected in its name which comes from “toramalli”, which means “mixed gems” in Sinhalese, a language of Sri Lanka. Tourmalines come in a broad variety of exciting colors and have one of the widest color ranges of any species of gemstones.

  • Rubellite is a type of tourmaline that includes red, purplish-red, orangy-red, and           brownish-red.
  • Indicolite is a dark violetish blue to greenish blue member of the tourmaline family.
  • Chrome Tourmaline is primarily colored by chromium and is often an intense green.
  • Watermelon Tourmaline is an interesting stone that is generally pink in the center and green around the outside of the crystal.

 

For many years gemologists would claim that tourmaline could be found in any color except vibrant blue, but in 1988 a truly remarkable blue variety of tourmaline was discovered in the state of Paraiba, Brazil. This gemstone, now known as Paraiba Tourmaline has become one of the most desired of all tourmalines with its intense violetish blue, greenish blue, or blue color.
