Beryllium is a chemical element with symbol Be and atomic number 4. It is created through stellar nucleosynthesis and is a relatively rare element in the universe. It is a divalent element which occurs naturally only in combination with other elements in minerals. Notable gemstones which contain beryllium include beryl aquamarine, emerald and chrysoberyl. As a free element it is a steel-gray, strong, lightweight and brittle alkaline earth metal.
