Member of the beryl family.

A mineral composed of beryllium aluminum cyclosilicate with the chemical formula Be3Al2(Si O3)6 .

Hardness is 7.5-8 Mohs.

The hexagonal crystals my be very small or range up to many meters in size.

Aquamarine (from Latin: aqua marina or “water of the sea”) is a blue or cyan variety of beryl. It occurs in most localities which yield ordinary beryl.

The blue color of aquamarine is attributed to Fe2+. The Fe3+ produces a golden yellow color. If both Fe2+ and Fe3+ is found, you get a darker blue which is known as maxxie. The color of maxxie can be reduced by light or heat thus causing a change in the charge changes of Fe2+ and Fe3+, it can be returned by irradiating the stone with high-energy particles, gamma rays, neutrons or even x-rays

It has been said that the mineral beryl gives the wearer protection against foes in battle or litigation. It makes the wearer unconquerable and amiable, and also quickens the intellect.

Since early times, aquamarine has been believed to endow the wearer with foresight, courage, and happiness. It is said to increase intelligence and make one youthful. As a healing stone, it is said to be effective as a treatment for anxiety and in the Middle Ages it was thought that aquamarine would reduce the effect of poisons.

A legend says that sailors wore aquamarine gemstones to keep them safe and prevent seasickness.
