This particular stone is from Batalha, Brazil, known as the birthplace of Paraiba tourmaline. With 2.0% CuO and 0.5% MnO, it features an impressive, signature Paraiba neon blue color. It is a round cut measuring approximately 3.0mm in diameter. Despite its small size, this Paraiba tourmaline boasts excellent color saturation, allowing you to enjoy a bright blue hue.
