Beryllium is the chemical element with the symbol Be and atomic number 4. Because any beryllium synthesized in stars is short-lived, it is a relatively rare element in the universe. It is a divalent element which occurs naturally only in combination with other elements. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl.
