Latin for "sea water," the aquamarine is known for its striking ice‐blue colour. Aquamarine has been mined and worn for thousands of years. Medieval sages suggested that water touched by aquamarine could cure a host of illnesses, including those affecting the eyes and lungs. The gem is also thought to bring foresight to its wearer.
