Uvite

Uvite is an uncommon form of tourmaline, and it forms different crystal formations than the most of the other tourmalines. Though it lacks the color diversity as some of the other tourmaline forms.  It does occur in beautiful green and reddish-brown crystals, as well as lustrous submetallic crystals. The name Uvite is derived from the type locality of the Uva Province, in Sri Lanka, where it was first identified.
