Historically, jewelry designers used precious metals to make their wares. Gold and silver resisted corrosion and were easy to form into intricate shapes, so many cultures prized them for jewelry and coinage. Their use in coins and high value as jewelry materials made gold and silver the first precious metals. Precious metals are those that are rare and valuable enough to serve as currency. These metals frequently overlap with the jewelry industry because the same properties that make a metal well suited for currency also make it ideal for jewelry.
