The studied beryl crystals came from the Julianna pegmatitic system exposed in the Dolnośląskie Surowce Skalne S.A. quarry at Piława Górna. This mineral occurs here in various forms and colours (green, yellow, white, pinkish and blue) in almost all pegmatite bodies. The paper describes the relationship between the structure and chemical composition of different coloured beryl crystals.
