Aquamarine, named for the Latin phrase “water of the sea”, is the blue to blue-green variety Beryl. Aquamarine ranges in color from a faint light blue to blue and bluish-green, with lighter colored stones being the more common type. Light green Beryl can be transformed into Aquamarine if heated to 750º F (400º C). The green hues in most Aquamarine can also be removed through heat treatment.
