Physical properties

Translucent pale blue-green, vitreous luster; hexagonal crystal system, Mohs hardness 7.5–8, no obvious cleavage. The photo alone cannot confirm the species or gem quality.

Formation & geological history

Beryl crystallizes in granitic pegmatites and some metamorphic rocks as magma cools; specimens may range from ancient to geologically recent, depending on deposit.

Uses & applications

Gem-quality aquamarine is cut for jewelry; common or fractured beryl is collected as a mineral specimen and can be an important beryllium ore.

Geological facts

Beryl’s color depends on trace elements: iron produces aquamarine’s blue-green hues, while chromium or vanadium can produce emerald.

Field identification & locations

Look for a hexagonal prism, vitreous surface, and hardness sufficient to scratch glass; color and shape in this irregular fragment are not diagnostic. Beryl occurs in pegmatites worldwide, including Brazil, Madagascar, and Pakistan.
