Aquamarine (from latin:
aqua marina, "water of the sea") is a blue or turquoise variety of beryl. It occurs at most localities which yield ordinary beryl. The gem-gravel placer deposits of sri lanka contain aquamarine. Clear yellow beryl, such as that occurring in Brazil, is sometimes called
aquamarine chrysolite.
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 is subjected to heat treatment,
though the color returns with irradiation.
