Physical properties

Formation & geological history

Usually found in granitic pegmatites or hydrothermal veins. Formed during the late stages of magmatic crystallization when beryllium is concentrated. Common in Precambrian and Paleozoic terrains.

Uses & applications

Primary source of beryllium for alloys in aerospace and telecommunications; significant use as a gemstone in high-end jewelry; prized by mineral collectors in its raw form.

Geological facts

The name comes from Latin 'aqua marina' (water of the sea). Ancient sailors believed it could calm waves and protect them at sea. It is the official birthstone for March.

Field identification & locations

Identify in the field by its distinct hexagonal crystal habit, lack of reaction to acid, and hardness. Common locations include Brazil, Pakistan, Madagascar, and the Ural Mountains in Russia.
