Named after the color of seawater, aquamarine is the blue to blue-green member of the beryl family. Readily available and moderately priced, the March birthstone makes an excellent jewelry stone.
The name "aquamarine" comes from the Latin for "seawater", and the stones were thought to protect seafarers. Some associate aquamarines with marital happiness and superior intellect.
These stones can be found in both blue and blue/green hues. Aquamarine stones will always have light color saturation and tone so you will not see any dark blues or greens.
