The more common forms are fairly inexpensive, but the rarer colors can bring astronomical prices. The most valuable Tourmaline is a very rare neon-blue called Paraiba. This Tourmaline was first discovered in 1989 in Paraiba, Brazil. The cost for this Paraiba became extremely high very quickly because the supply was so limited. Small deposits of Tourmaline of similar color to Paraiba Tourmaline were subsequently found in Nigeria and Mozambique and a huge uproar occurred in the gem world when suppliers called these "Paraiba Tourmaline" as well.
Other valuable forms of Tourmaline are Chrome Tourmaline, an intense-green Tourmaline found in Tanzania, Rubellite, the pink to red variety, and 

Indicolite, the rare blue variety.
Just recently new finds in Madagascar, Namibia, Mozambique, Tanzania and Nigeria, and have made these countries big producers of gem quality Tourmaline.
