Beryllium is a solid silvery-grey metal at normal pressure and temperature, it is very strong to cut or break differently from his cousins the alkali metals.
Beryllium is relatively inert and very light metal. It is nearly transparent for X-rays. Beryllium is not often used, as it quite expensive and toxic. However it is an important ingredient in many valuable gemstones, like beryl, aquamarine and emerald. Clear beryl was used for optical lenses in former times.
