Aquamarine is the blue variety of beryl (green beryl is emerald, pink beryl is morganite). Aquamarines come in a range of colors including dark blue, sky blue, blue-green, and blueish-grey. Today, the most desirable colors are sky blue and dark blue; however, in the 19th century the preferred color was sea green. The best gem quality aquamarines are found in Brazil. Most aquamarine gems have been heat treated to enhance the color.


The majority of aquamarine is found in Brazil. Aquamarine is also found in Angola, Kenya, Madagascar, Malawi, Mozambique, Nigeria, Pakistan, Russia (Ural Mountains), Tanzania, the United States (California and Colorado), and Zambia.


  • Aquamarine is derived from Latin aqua marina meaning “sea water”.
  • The largest aquamarine ever was found in Brazil weighing 243 pounds! It was cut into smaller gemstones yielding over 200,000 Carats in total.
  • Historically, sailors would take an aquamarine stone on long voyages to protect against accidents and seasickness.
  • The Dom Pedro Aquamarine, the world’s largest cut aquamarine, is displayed in the Smithsonian National Museum of Natural History.


Aquamarine is rated a 7.5-8 on the Mohs scale of hardness. This makes aquamarine suitable for every day wear. While we always recommend professional cleaning, aquamarine jewelry may be safely cleaned at home with warm soapy water and a soft brush.
