Gold futures on the COMEX division of the New York Mercantile Exchange closed lower on Friday, with the precious metal failing to find safe-haven support from the U.S.-China trade frictions, as the U.S. dollar gained for the week.

The most active gold contract for August delivery went down 5.4 dollars, or 0.43 percent, to close at 1,241.2 dollars per ounce.

The U.S. dollar index, which measures the buck against six rivals, went down 0.08 percent to 94.76 as of 1930 GMT. However, the U.S. dollar boasts a weekly gain of 0.8 percent.

Gold usually moves in opposite directions with the U.S. dollar, which means if the dollar goes up, gold futures will fall as gold, priced in U.S. dollar, becomes more expensive for investors using other currencies.

As for other precious metals, silver for September delivery fell 16.2 cents, or 1.01 percent, to settle at 15.815 dollars per ounce. Platinum for October dropped 16.1 dollars, or 1.9 percent, to close at 830.3 dollars per ounce.
