Aquamarine gemstones call to mind the colors of the sea. Aquamarine can be blue, very slightly greenish blue, or green-blue. Aquamarine gemstones are often free from inclusions and clear as water too, symbolizing purity of spirit and soul. They make fantastic gemstones for evening wear because they glitter and gleam even under muted light conditions. During the day or in bright light, they exhibit a soothing coolness. Aquamarine is the March birthstone, but anyone can wear and delight in the optical qualities of this gemstone.
