According to legend, aquamarine originated in the treasure chest of fabulous mermaids, and has since ancient times, been regarded as ‘the sailor’s lucky stone’. Aquamarine derives its name from the Latin term for seawater and has a long tradition of being a stone for those who spend much of their time at sea. The Greeks and the Romans knew aquamarine as the sailor’s gem too, believing that it ensured a safe and prosperous passage across stormy seas. Legend has it that aquamarines were the prized possessions of many mermaids and would thus protect sailors from the dangers of sea, including warding off sea-sickness.
In Antiquity, as well as in the Middle Ages people believed that the cosmos is reflected in gemstones. It is no surprise that aquamarine is assigned to the planet Neptune and is also one of March’s official birthstones. The esoteric movement revived the ancient belief and the gem industry made it another marketing tool to promote certain gems.
