What is a Paraíba Tourmaline?
Paraíba is a variety of elbaite tourmaline with copper content. The name comes from the Brazilian state of Paraíba, the original source. Subsequent discoveries of similar stones in Nigeria and Mozambique caused some controversy over the use of this name. The gem community largely accepts paraíba as a variety name. Nevertheless, some gem dealers may refer to the gems that come from Africa as “paraíba-like” or cuprian tourmalines. However, laboratory reports from major gemological laboratories note that paraíba refers to copper content, not locality.
Furthermore, the GIA’s identification of cuprian liddicoatite in 2017 from unknown sources may expand the definition of paraíba tourmaline to include other cuprian gem species of tourmaline.
