You can almost hear the roaring waves when you stare into the shimmering facets of aquamarine jewelry. The gem of the sea, aquamarine embodies the spirit of the ocean, from the playful lightness of its shallows, to the mysterious secrets of the deep. Aquamarine is the birthstone of March, and is so brilliant that it rivals diamonds in its beauty. An aquamarine ring is an ideal gift for a March birthday. Aquamarine earrings and pendants will work just as well to please even the most finicky recipient.
