The birthstone of March, the Aquamarine is a type of beryl – putting it in the same family as Emeralds and Morganites. Aquamarines come in shades of blue-green, and most commonly have a very light blue color reminiscent of a pool of sparkling clear water. Their name comes from the Latin phrase aqua marina, meaning “sea water," no doubt inspired by the stone's natural clarity and transparency. The most valuable Aquamarines have a deep blue-green color.

Aquamarine crystals can be very large, with some natural stones weighing up to 100 pounds. They can be found in Brazil, Africa, Pakistan and Vietnam.
