Vorobyevite

is a recently discovered beryl containing Cesium as impurity with formula Be3Al2(Si6O18) .

There is debate regarding Pezzottaite vs Vorobyevite and choromophores , Cesium cannot be responsible for any colors, instead the bluish color of Vorobyevite is due to iron traces,as far as I know.This question remain open and more studies need to be done in order to find out the true.
