But gold prices scored a gain for the week as the market mulled recent data from China and the U.S. for signs of investor demand. February gold fell $3.80, or 0.2%, to settle at $1,687 U.S. an ounce on the Comex division of the New York Mercantile Exchange. It gained 1.6% for the week. March silver settled at $31.93 U.S. an ounce, up 0.4% for the session and up 5% from a week ago.
