 The word aquamarine symbolizes the deep blue waters of the sea. Aqua means ‘water’ and marine means ‘of the sea’. The name obviously comes from the fact that all aquamarines are blue in color. The gem owes its name and popularity to the unique color that it has. This blue gemstone is the birthstone for the people born in the month of March and hence called as the March Birthstone.


The aquamarine rough was first mined in 1811 in Brazil. However, history has it that it has been used in jewelry much before this time. One of the first documented proofs of the use of aquamarine gemstones exists between 480 and 300 BC. This gem was used by the Greeks to make aquamarine jewelry. In the middle ages, people believed that this gem stone could magical overcome the effects of poison.

Pirates and sailors used small opaque and translucent aquamarine rocks and (some times good quality aquamarine crystals too) as amulets and believed that it would protect them from the raging sea and ensure a safe return. In some parts of the world the aquamarine birthstone is considered to be a symbol of eternal youth, joy and happiness.
