Chrysoberyl

The gem commonly known as chrysoberyl is a yellowish-green, brownish-yellow, or colorless transparent to translucent mineral that is usually faceted into gems and generally considered a collector's stone. While not often set in jewelry, its characteristics make it ideal for such use.

Chemically, it is a mixed oxide of beryllium and aluminium. It has the chemical formula BeAl2O4.[1] Chrysoberyl is not a type of beryl, which is a beryllium silicate.
