Deo Darrah (Persian word meaning Valley of Jin) is an old tourmaline mine.

Blue beryl from this locality was originally described as vorobyevite, however analysis has shown no noticeable Cs level (but with higher levels of Na and Ca) so it is essentially an alkali-rich beryl. See http://www.mindat.org/mesg-11-310231.html and http://www.mindat.org/forum.php?read,105,351767,page=1. Analyses of rosettes of tabular aquamarine from "Kuran, district Wamunjan" (probably from Deo Darrah) reported in Weerth & Weiß (2016) show, apart from Na, increased levels of iron (~1.5 wt.% FeO) and cesium (~0.15 wt.% Cs2O), plus traces of scandium (~0,01 wt.% Sc2O3).
