A toenail-sized specimen of uvite tourmaline. The olive-toned crystal measures about 1.75 cm, and is doubly-terminated (with a superb glassy termination on top) and super-lustrous. These colorful, olive-yellow uvites are the rarest color varietal of all from the locality (more so even than the red varietal). 3.3 x 2.7 x 1.8 cm.
