Rubellite is a name for pink, red, purplish red, orangey 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 colours many Brazilian and African emeralds.
