This article is about the mineral. For other meanings, see Aquamarine (disambiguation). Aquamarine Aquamarine (Lat. aqua marina, "water of the sea") is a gemstone-quality transparent variety of beryl, having a delicate blue or bluish-green colour, suggestive of the tint of sea-water. It's closely related to the emerald. It occurs at most localities which yield ordinary beryl, some of the finest coming from Russia. The gem-gravels of Ceylon contain aquamarine. Clear yellow beryl, such as occurs in Brazil, is sometimes called aquamarine chrysolite. When corundum presents the bluish tint of typical aquamarine, it is often termed Oriental aquamarine. In the United States, aquamarines can be found at the summit of Mt. Antero in the Sawatch Range in central Colorado. In Brazil, there are mines in the states of Minas Gerais, Espírito Santo and Bahia. The biggest aquamarine ever mined was found at the city of Marambaia, Minas Gerais. It weighed over 110 kg, and its dimensions were 48.5 cm long and 42 cm in diameter. Aquamarine is the birthstone associated with March.
