March Birthstone - Aquamarine


Aquamarine comes from the Latin word for "sea water". It is the greenish blue to blue-green variety of the mineral beryl. In the Middle Ages, aquamarine was believed to help the wearer conquer all wickedness, and it was also prescribed for eye trouble, respiratory disease and hiccups.

Aquamarine is also a symbol of happiness and everlasting youth. The typical size range of aquamarine is wide, and stones are commonly seen in 10-30 carat sizes. Faceted stones of more than 1000 carats are also known to exist. It is possible for some aquamarine to exhibit chatoyancy (a cat's eye effect).
