Chrysoberyl is a hard, tough and durable stone. Chrysoberyl gemstones are not treated or enhanced. There are three main varieties of chrysoberyl: yellow-to green-chrysoberyl, cat's eye chrysoberyl and alexandrite.

When chrysoberyl is transparent with a good green to yellow color it is used as a gemstone. When chrysoberyl gets polished into a cabachon and displays a sharp line of light through the center of the stone it is Cat's eye chrysoberyl. This line of light is caused by microscopic needle-like fiber inclusions that cause the light to band toghether in a thin streak.
