Beryl was discovered in a feldspar-rich pegmatite with thick graphic and partially albitized blocky rose microcline zones (Fersman, 1962).
Highly corroded prismatic crystals of bottle-green and yellow-green
beryl up to 18 cm long, were found in the albitized parts of microcline-perthite and in miarolitic cavities filled with whitish clay. Subhedral grains of opaque bluish
beryl were also found in the vein.
