More Information about Aquamarine
Aquamarine is a pastel greenish-blue variety of the mineral beryl and owes its color to the presence of iron impurities. Its name is derived from the Latin words for water (aqua) and sea (marine). Crystals form in large hexagonal prisms. In ancient times, it was believed that sailors wearing aquamarine pendants would be protected from the perils of the sea. The stone symbolized happiness and eternal youth. It was viewed in Christian symbolism to bring moderation and control of passions to its owner.

Care
Although aquamarines require no special care and can resist scratching from everyday wear very well, cut-corner designs and protective settings can still help them resist chipping and breaking.
However, inclusions within aquamarines may not react well to mechanical cleaning techniques like ultrasound or steam, increasing the risk of shattering. Therefore, consult with a gemologist first to determine if your gems can withstand these cleaning methods. Of course, you can always use a soft brush, mild detergent, and warm water to clean your aquamarines safely.
