Physical properties

A tiny, translucent pale green fragment with a vitreous luster. Beryl has Mohs hardness 7.5–8 and a hexagonal crystal structure; the photo does not show diagnostic crystal form or cleavage clearly.

Formation & geological history

Beryl typically crystallizes in granitic pegmatites and some metamorphic rocks as silica-rich magma cools; deposits range from Precambrian to recent geological settings.

Uses & applications

Gem-quality aquamarine is cut for jewelry; common beryl may be collected, while beryl is also an important source of beryllium.

Geological facts

Aquamarine is the blue-to-green variety of beryl; color alone cannot confirm this identification in such a small specimen.

Field identification & locations

Look for a hexagonal prism, glassy luster, and hardness sufficient to scratch quartz; common sources include Brazil, Pakistan, Madagascar, and the United States.
