“Aquamarine” comes from the Latin aqua marina meaning "water of the sea" for its blue or cyan colour. The pale blue colour of aquamarine is attributed to iron deposits.
Legend says that the King of the Sea, Neptune, gave aquamarine as gifts to mermaids – since then it has brought love to all who have owned it. Aquamarine is thought to have a calming influence on married couples, making it a good anniversary gift. Aquamarine is found in a range of blues, from a light pastel to a greenish-blue to a deep colour – darker shades are rare and therefore make the value increase.
