Physical properties Beryllium is a hard, brittle metal with a grayish-white surface. It is the least dense (lightest) metal that can be used in construction. Its melting point is 1,287°C (2,349°F) and its boiling point is estimated to be about 2,500°C (4,500°F). Its density is 1.8 grams per cubic centimeter.

Beryl is a beryllium aluminium cyclosilicate. It consists of beryllium and aluminum metals and rings of silicates. It's often colorless, but it's also frequently colored by impurities. It has prismatic crystals which may be pyramidal or transparent. This stone also has a vitreous, translucent, or transparent luster.

However, beryllium was not used extensively until a 1920s' discovery that 2% addition of beryllium to copper produced an alloy six times stronger than the original material. Beryllium is mined primarily from naturally occurring silicates including beryl (Al 2 Be 3 Si 6 O 18, 5% beryllium by weight) and bertrandite (Be 4 (OH) 2 Si 2, 15%
