• Aquamarine has a distinct greenish blue to blue color. Unlike emerald, light-colored stones in this color range are still called aquamarine. The stones that are richly colored are the most desirable, and the stones with a very pale color are made into inexpensive jewelry. Aquamarine differs from emerald in another way - it normally has far fewer inclusions and fractures.
