Aquamarine is the green-blue to blue variety of the mineral beryl. (Emerald is the green to bluish green variety of the same mineral.) Its color is usually a light pastel greenish blue.
The name “aquamarine” is derived from two Latin words: aqua, meaning “water,” and marina, meaning “of the sea.” It is said that it gives the wearer protection against foes in battle or litigation. It makes the wearer unconquerable and amiable, and also quickens the intellect.
This gemstone is mined mainly in Brazil, but it is also found in Nigeria, Madagascar, Zambia, Pakistan, and Mozambique.
The largest gem-quality aquamarine crystal mined to date is 19 inches long and weighs 110kg. It is named the Dom Pedro.
