The aquamarine's name is derived from Latin aqua marina, meaning "water of the sea". It is a blue or cyan variety of beryl and occurs at most localities which yield ordinary beryl. The deep blue version of aquamarine is called maxixe. Maxixe is commonly found in the country of Madagascar. Its color fades to white when exposed to sunlight or heat.
In the United States, aquamarines can be found for example at the summit of Mount Antero in the Sawatch Range in central Colorado, in Wyoming in the Big Horn Mountains near Powder River Pass, and in the Sawtooth Range near Stanley, Idaho. In Brazil it has been discovered in the states of Minas Gerais, Espírito Santo, and Bahia, and minorly in Rio Grande do Norte. Other locations are in Sri Lanka, Colombia, Zambia, Malawi, Tanzania and Kenya.
The largest aquamarine of gemstone quality ever mined was found in Marambaia, Minas Gerais, Brazil, in 1910. It weighed over 110 kg, and its dimensions were 48.5 centimetres long and 42 centimetres in diameter.
