| Comments: | Beryl is mostly earthy-white, greenish, occasionally yellowish, with or without iron oxide stainings, particularly along fractures. It occurs in various sizes ranging from tiny to large euhedral crystals. It exhibits a columnar habit, representing a combination of hexagonal prism and a pinacoid. Often, euhedral crystals measuring from 1 cm in length and less than 1 cm in width to 30 cm in length and 15 cm in width have been found around the quartz core. In places, well-developed prismatic crystals occur within the quartz core, which vary in size from 1 cm in length and less than 1 cm in diameter to 10 cm in length and 10 cm in diameter. Twinned and zoned crystals are also present. Significantly, abundant beryl crystals of different sizes have also been found studded within perthite zones. | |||||||||||||||||||
