Aquamarine gemstones evoke the colors of the sea. Aquamarine can be blue, very slightly greenish blue, greenish-blue, very strongly greenish blue, or green-blue. Aquamarine gemstones are often free from inclusions and clear as water too, symbolizing the 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.
