Aquamarine is a pretty unique stone. Its most valuable color is a dark blue to slightly greenish blue with moderately strong intensity. In general, the purer and more intense the blue color, the more valuable the stone. Most aquamarines are a light greenish-blue, but there are few shades of this color. This one is medium aquamarine. By the way, aquamarine gemstones sometimes can be easily confused with blue topaz, aquamarine is much more rare and valuable, just like our Aquamarine Pixel cursor pack.
