Physical properties

Pale green-blue, translucent crystals with a vitreous luster and hexagonal structure; Mohs hardness 7.5–8, with no distinct cleavage. The specimen appears attached to a darker, mica-rich matrix.

Formation & geological history

Beryl typically crystallizes in granitic pegmatites from late-stage, volatile-rich magma; individual deposits range widely in age, commonly Precambrian to younger. Blue-green color comes chiefly from trace iron.

Uses & applications

Gem-quality aquamarine is cut for jewelry; beryl is also collected as mineral specimens. This rough, matrix-bearing piece is primarily of collector interest.

Geological facts

Beryl’s chemical composition is shared by emerald, aquamarine, morganite, and other varieties; trace impurities produce their different colors.

Field identification & locations

Look for vitreous, translucent green-blue crystals and a six-sided prismatic form, often in pegmatite with quartz, feldspar, or mica. Common sources include Brazil, Madagascar, Pakistan, and Afghanistan; the photo alone cannot confirm locality or gem variety.
