Abstract
Beryl samples from Ukraine (Volyn) and Finland (Luumäki), associated with miaroliticpegmatites in Proterozoic rapakivi granites were studied by electronic microprobe analysis, X-ray diffraction, optical and infrared (IR) spectroscopy. Previous studies demonstrated the similarity of their crystallization conditions, physical parameters, inclusions and gemological characteristics.

Keywords: beryl, crystal chemistry, IR spectra, inclusions, chamber pegmatites.
