Paraiba tourmaline is a variety of elbaite, which in turn belongs to the tourmaline group. Decisive for the differentiation from other tourmalines is the chemical composition of the mineral.

The Paraiba tourmaline in the beautiful blue color (“Swimming Pool Blue”) is hardly found in blue color since years. Increasingly, the green varieties are also in demand. Moreover, hardly any blue Paraiba tourmalines more than 2 grams have been found in Brazil. The original main mine has closed, only individual farmers are still searching for material. The main place of discovery is Mozambique.
