Chrysoberyl (A1 2 BeO 4 ) and alexandrite (Al 2 BeO 4 :Cr) crystals have been grown successfully by the flux‐melt method in lengths from 0.1 to 10.0 mm. A satisfactory composition for chrysoberyl is PbO 66.6, A1 2 O 3 16.7, and BeO 16.7 mole yo; for alexandrite, LizMoOQ 40.4, MooB 50.6, A1 2 O 3 :Cr 4.5, and BeO 4.5 mole yo. Morphological characteristics of the crystals produced are described.
