Loose natural Brazilian paraiba tourmaline, that most rare of tourmalines and gems, is famed for its unique neon Caribbean blue colour. These Brazilian Paraiba tourmalines caused a sensation when they first appeared in the late 1980s. The deposit from when they came was very small and quickly dugout. This saw the prices for natural Brazilian paraiba tourmaline skyrocket almost overnight. They have since become one of the most sorts after gems in the mineral kingdom.
