Deep blue Paraiba tourmaline from Brazil. Historically, Paraiba was mined in Brazil. However, today the deposits of Brazil are almost depleted and 99% of Paraiba in the world jewelry market is mined in Mozambique, so it is a great success to find such a specimen!
This tourmaline is cabochon cut and has a very rare deep blue color. The stone has an impressive weight of 4.65 carats for Brazil.
This Paraiba tourmaline has a purity upgrade - impregnation. Due to the fact that Paraiba from Brazil is incredibly rare, this kind of refinement is acceptable and necessary to preserve the integrity and size of the stone when cutting.
