Haramosh Peak, Haramosh Mts., Roundu District, Gilgit-Baltistan, Pakistan

The pegmatites of the Haramosh field commonly have peripheral fine-grained granite or alpite margins and coarse-grained central areas with vugs and miarolitic cavities from 5 cm to 1 m across. Transparent pale-blue gem-quality crystals of beryl, accompanied by euhedral feldspar, quartz, schorl, and mica are found in cavities and may form part of the pegmatite matrix.
