Beryl (Cs-bearing)


The name beryl derives from the ancient Greek word beryllos, a blue-gem gem. Analyses of beryl by Vauquelin (1798) revealed the presence of a new metal, which Wöhler (1828) and Bussy (1828) bothindependently isolated. Wöhler's name for the element, beryllium, comes from the mineral name. This is a composite crystal of pink cesium-rich beryl. These particular specimens occur in the same pegmatites as the popular Burmese mushroom tourmaline. The rich pink color results from Mn3+ ions substituting for Al in the crystal structure.
