Accompanied by an American Gemological Laboratories report numbered 1117786 dated October 5, 2021 stating that the 33.33 carats pear-shaped tourmaline is a paraiba-type tourmaline and that it originates from Mozambique. "Paraiba-type" is a term/color variety applied by the AGL to the copper-bearing variety of elbaite tourmaline, which was first discovered in the Paraiba state of Brazil, but may have originated from a different source. The color is natural and there is no clarity enhancement. Non-heated paraiba-type tourmalines are scarce.
