A single gemmy deep bottle green to vivid chromium green Dravite Tourmaline crystal measuring to 2.8 cm from the Nadonjukin area in mid-northern Tanzania. This material was originally described as Chromium enriched, or Chrome Dravite, but the green colouration is now known to be due to a small percentage of Vanadium with a small yellowish core. Hence it is now referred to as vanadium enriched Dravite, Dravite being a member of the Tourmaline Group.
