A gemstone named for the sea
Aquamarine takes its name from the Latin words for seawater. Stories of sailors carrying it as a protective talisman belong to its folklore. In jewelry, its appeal comes from its color, transparency, and the light reflected by a well-chosen cut.

Choosing your aquamarine
Clarity and cut
Many faceted aquamarines are eye-clean, but inclusions can occur. Look for an attractive face-up appearance and proportions that show the stone’s color and brightness.

Care
Aquamarine is suitable for jewelry when protected from scratches and hard knocks. Warm water and mild soap are a good cleaning choice. Avoid heat exposure; stones with fractures, fillings, or liquid inclusions may be unsuitable for ultrasonic or steam cleaning.
