The extremely rare paraiba tourmaline, found first in Brazil, later in Nigeria and Mozambique, is typically a small neon blue or green gem. Most tourmalines get their colour from traces of iron, chromium and vanadium, but the paraiba has traces of copper, and often manganese. Their perfect interaction enhances the fascination. This saturated, swimming pool blue, flawless 15-carat paraiba tourmaline is one of the best ones ever found. A very attractive gem.
