This is a lustrous, transparent, green dravite tourmaline, 2.5 cm in length, weighing 66.65 carats, crystallized on transparent quartz. This specimen has been contacted, mainly on the back side, nevertheless, its depth of color and transparency are outstanding. Tourmaline of this intense hue, due to vanadium with perhaps a bit of chromium, is just incredibly rare.
