Aquamarine beryl is a transparent, pale blue to blue-green variety of the beryl mineral family. Its distinct color, which ranges from light aqua to deeper blue tones, is due to trace amounts of iron. Aquamarine is prized for its clarity, often displaying minimal inclusions, which makes it ideal for faceting into gemstones. With a hardness of 7.5 to 8 on the Mohs scale, it is durable enough for daily wear in jewelry.

The gemstone's name comes from the Latin aqua marina, meaning "sea water," reflecting its clear, ocean-like hues. Aquamarine beryl is commonly found in Brazil, Madagascar, and Zambia, with the finest examples being a vivid blue without greenish tint. Throughout history, aquamarine has been linked to soothing, calming energies and was believed to protect sailors on their voyages.
