Yellow Dravite from Tanzania

Abstract

During the 2016 Tucson gem shows, Todd Wacks (Tucson Todd's Gems, Tucson, Arizona, USA) showed author BML a yellow 11.13 ct tourmaline that he faceted from a piece of rough recently obtained on a buying trip to Tanzania by Sir-Faraz Ahmad (Farooq) Hashmi (Intimate Gems, Glen Cove, New York, USA). The rough material was reportedly found in October–November 2015 in the Landanai region of north-eastern Tanzania, in an area that is known for producing green 'chrome' tourmaline. The rough consisted of a round 'nodule' that showed a few crystal faces. In faceting the gemsone, Wacks cut a small table and a deep pavilion to maximize the colour appearance.
