Aquamarine gemstones evoke the colors of the sea. Aquamarine gemstones are often free from inclusions and clear as water too, symbolizing purity of spirit and soul. They make fantastic gemstones for evening wear because they glitter and gleam even under muted light conditions. During the day or in bright light, they exhibit a soothing coolness.

Aquamarine belongs to the beryl species of mineral and is closely related to emerald, morganite and golden beryl, among others. Nature produces a variety known as cat’s-eye aquamarine, a rare, highly collectible, phenomenal variety. Microscopic growth tube inclusions cause the cat’s-eye effect.

Aquamarine is the March birthstone.


Aquamarine can be blue, very slightly greenish blue, greenish blue, very strongly greenish blue, or green-blue.


Aquamarines can be cut into many shapes and sizes; some are cut as cabochons or fashioned into beads. Larger specimens may be carved into gem sculptures.


Aquamarines are found on most continents. Brazil is an important source for aquamarine. Other sources include Afghanistan, Burma (Myanmar), China, Kenya, Madagascar, Mozambique, Ukraine and the United States.


Aquamarine is a fairly durable gemstone with a hardness of 7.5-8.0 on the Mohs Hardness Scale


Aquamarines are almost always heat-treated to lessen the subtle yellow color that occurs in some of them. Any treatments should be disclosed to buyers.


Aquamarine can be manufactured in a lab rather than mined, but it is more often imitated by treated blue topaz, glass and synthetic blue spinel. This information needs to be clearly disclosed to the buyer.
