AbstractFive specimens of beryl and alkali-rich beryl with different alkali contents and one specimen of pezzottaite have been studied by 29Si, 9Be, 27Al, 23Na, 133Cs, 7Li and 1H MAS NMR spectra at 9.4 T, to find structural relationships between these minerals. We have found that the structure alkali-rich beryl is intermediate between the structures of alkali-poor beryl and pezzottaite. In addition, the NMR data of these structures are not fully consistent with available lattice models from reciprocal-space techniques.
