Aquamarine
Aquamarine's name comes from the words "aqua" and "mare," meaning water and sea, from its intense blue-green color. Because of its resemblance to the ocean, sailors used to wear talismans made of aquamarine depicting the god Neptune, who ruled the seas. With the help of their god, they believed the aquamarine would offer them protection from the elements. As far as lore goes sailors carried Aquamarine for protection from drowning or other accidents whole at sea, in today's world it is often carried for the purpose of safe travel over water and in fact it is a useful stone for those who suffer from Nausea as a consequence of Motion or Travel Sickness.
