Aquamarine, the March birthstone, is said to bring happiness to a marriage, calm waves, and keep sailors safe at sea: not surprising for a gem named after seawater. Aquamarine’s tranquil blues conjure peaceful waters and smooth sailing.

Not only is aquamarine one of the March birthstones, it’s also used to celebrate 19th wedding anniversaries. It is most often light in tone and ranges from greenish blue to blue-green; the color usually is more intense in larger stones, and darker blue stones are very valuable.
