Neon Tourmaline from Nigeria
This month we have a special tourmaline from Nigeria. It is a very rare copper-bearing neon-blue tourmaline that can be referred to as paraiba. This stone has been heated to show off its beautiful neon blue. The color is the result of traces of copper and manganese. This stone hosts a ghost-like platelet that is an indicative inclusion—proof of its Nigerian origin. Weighing in at 4.18 carats this stone is rather large for its clarity and color. Most Nigerian stones available are in a smaller range with more distracting inclusions throughout.
