Aquamarine stones have excellent clarity and transparency compared to many other similar gems, and is exceptionally hard with a vitreous glass-like luster. The intensity of color and the clarity of the stone are the most important criteria when evaluating aquamarine, followed by quality of cut. The lucid color of aquamarine makes it easy to see inclusions. For this reason, aquamarine should always be of the greatest possible transparency. Iron is the substance which gives aquamarine its color, which ranges from an almost indiscernible pale blue to a strong sea-blue. The name Aquamarine was derived from an old Latin expression which meant seawater. The more intense the color of an aquamarine, the more value is put on it.
