Aquamarine natural crystal pendant 2.4g, Afghanistan

Aquamarine is a hexa-mineral, beryllium aluminosilicate (chemical formula Be3Al2Si6O18). The name of the mineral is derived from the Latin aqua marina (sea water).
Aquamarine is a variety of beryl. It is light blue to green-blue. It is used as a gemstone in the jewelery industry, most often faceted, possibly also in the shape of cabochons. The world's aquamarine sites include Brazil (Minas Gerais), USA, Pakistan, Sri Lanka, Madagascar, Namibia, and more.
In ancient legends, aquamarine was most often associated with the goddess of the sea, Amphitrite, who was the wife of Poseidon, and also with the goddess Aphrodite, which was rumored to have been born of sea foam. Another legend says that aquamarine comes from the treasury of mythical mermaids. Obviously, since then, aquamarine has been considered a seafaring stone for good luck.
