Moreover, the GIA’s identification of cuprian liddicoatite in 2017 from unknown resources may well expand the definition of paraíba tourmaline to include other cuprian gem species of tourmaline.
On account of how stunning and one of a kind these gemstones have been, they have got very sought after. Very similar tourmaline deposits had been uncovered afterward in other areas of Brazil in addition to in Nigeria and Mozambique.
