Aquamarine

Aquamarine is another of the gems composed of Beryl. It occurs in colors of light sky blue, greenish blue, or greenish yellow. The light sky-blue stone is the one of the most value, and is very brilliant, especially by artificial light. The color of the aquamarine may be altered by various artificial means, and experiments along this line have been undertaken for many years by some of the German universities, resulting in the discovery of a method by which in rare cases the less valuable greenish-blue variety may be changed to a shade of light sky blue of great value without altering the stone to any perceptible degree.
