Aquamarine
The Sea-Clear Voice of Courage
About the stone

Aquamarine is the blue to greenish-blue variety of beryl, treasured as a gemstone since antiquity; its name comes from Latin words meaning “water of the sea.” Because it was known to ancient cultures, no single discoverer or discovery date is recorded, and Roman fishermen used it as a protective talisman for sea travel. Important sources include Brazil’s Minas Gerais region, which has supplied aquamarine for roughly two centuries, and Pakistan’s Karakoram Mountains. In traditional lore, aquamarine was believed to calm waves, safeguard sailors, and bring happiness to marriage.

Care and handling

Its color is delicate and can fade after prolonged direct sun exposure, so store it away from bright light. Avoid sudden temperature changes, and take care with fractured or included stones in ultrasonic cleaners.
