Since its discovery in Brazil in 1989, Paraíba tourmaline’s striking range of color has electrified the gem world. Its hues include blue (electric blue, neon blue, violet blue), bluish green to greenish blue, and green (or yellowish green). The gem’s vivid colors instantly set it apart from other tourmaline varieties. Initial worldwide reception to Paraíba tourmaline was intense, especially in Japan, where demand for fine-quality gems was insatiable. Paraíba tourmaline was also discovered in Nigeria and Mozambique. The gems seen here are from Nigeria.
