Gold fell as the dollar advanced, diminishing the precious metal's appeal as an alternative investment.
The actively traded August contract for gold fell $14.70, or 1 percent, to $1,397.20 an ounce.
Gold has dropped 17 percent this year as the dollar and U.S. stocks have risen, reducing demand for safe-haven assets. The precious metal is unlikely to see any pickup in demand if stock markets remain close to their record levels, said Adam Klopfenstein, a senior market strategist at Archer Financial Services.
