Aquamarine

Description

Found in green-blue to blue color variations, aquamarine crystals get the blue tone due to the presence of iron within the crystal. They are comparatively large and well-formed and the depth of sea blue color is most intense in large specimens while the color in smaller stones is comparatively lighter. Unlike other colored gemstones, aquamarine’s value comes primarily from its tone rather than the hue and saturation, and stones with darker tones are highly priced and sought after.
