Gold fell to a 2-1/2 week trough on Tuesday, moving down with other precious metals due to a session high in the dollar index and better appetite for assets seen as higher risk, such as European stocks.
Silver also dipped to its lowest since mid-August at $27.53 an ounce, while platinum and palladium lost more than one percent.
Spot gold fell as low as $1,579.50 an ounce, its weakest since March 14, and was down 1.1 percent at $1,580.99. The metal was on track for its biggest one-day loss since a 2.6 percent slide on February 20.
U.S. gold futures were down $17.30 to $1,583.70 an ounce.
