Mithril

Mithril is a metal sometimes even called silver steel. Some people like to call it true silver or Moria silver. It is a very precious and silvery metal, stronger than stell but much lighter in weight. It is found in Khazad-dum where it is mined by the dwarves. It was also found in Numenor. Most people desired the mithril because it was worth ten times as much as gold and could be beaten like copper and polished like glass. Also the beauty of it didn't tarnish or grow dim.
