Physical properties

Formation & geological history

Beryl forms in pegmatites and some hydrothermal veins; aquamarine-bearing deposits occur in Brazil, Madagascar, Pakistan, and elsewhere. The bracelet’s beads are cut and polished from mined material; the mineral may be millions to billions of years old.

Uses & applications

Aquamarine is used in jewelry and as a collectible gemstone; beryl also has limited industrial use as a beryllium ore.

Geological facts

Aquamarine is the blue-to-blue-green variety of beryl; its name derives from Latin for “water of the sea.”

Field identification & locations

Look for natural inclusions, glassy luster, and hardness, but gem testing is needed to distinguish it from look-alike materials. Beads are commonly drilled and polished, obscuring crystal form.
