The March birthstone is Aquamarine
Aquamarine, or “aqua”, is a light greenish blue gemstone named after “seawater” in Latin. When worn, it is said to keep sailors safe and “calm the waves” at sea. Aquamarine is also thought to enhance the happiness of marriages. Traditionally, it is given as a 19th wedding anniversary gift.
Aquamarine is a beryl so it is in the same mineral family as emeralds. It is mined in high elevations. The largest gem-quality aqua crystal mined was 19 inches in length and it was found in Marambaia, Minas Gerais, Brazil, in 1910.
