Notes:
Beryllium is very rare. Its principal ore is beryl, a complex aluminosilicate.
When beryl has traces of chromium impurities, it's the emerald. When beryl
contains traces of iron it's aquamarine. Beryllium does not occur free in
nature. Beryllium is primarily used in alloys, esspecially copper to form
non-sparking tools.
