A major interest in beryllium minerals, which are rock-forming constituents in certain metamorphic, hydrothermal and igneous environments, comes from their use as ore materials for Be, as single-crystal material for special optical purposes, and as gemstones. Beryl, ideally Al₂Be₃Si₆O₁₈, bertrandite, Be₄Si₂O₇(OH)₂, and phenakite, Be₂SiO₄ are mined and processed as ores of Be. Beryl and chrysoberyl are used as maser and laser crystals, and bromellite BeO has outstanding properties such as exceptionally high electrical conductivity and speed-of-sound propagation in combination with great...
