With colors ranging from light blue to dark blue and even blue-green, aquamarine has been linked to water and the seas throughout history.
Roman fishermen called the gemstone “water of the sea” and used it as protection, for safe travel by boat, and for luck in catching fish. Aquamarine was linked to the apostle St. Thomas who frequently traveled by boat. Roman physicians also used it to treat overeating and bloating.
The Sumerians, Egyptians, Hebrews, and Greeks all admired aquamarine gemstones. Beads were discovered with Egyptian mummies. And it was believed that the High Priest of the Second Temple wore aquamarine stones engraved with the six tribes of Israel. Two thousand years ago, people in Greece engraved designs into aquamarine stones, turning them into intaglios.
