A one kilogram gold bar sits on top of silver bars at London bullion dealers Gold Investments in London, United Kingdom, on April 4, 2013.

Gold retreated on Wednesday, hit by a bout of technical selling after it failed to hold above the key $1,800 level as investors looked past a subdued dollar and sought clarity on the U.S. Federal Reserve's tapering strategy.

Spot gold fell 0.6% to $1,793.81 per ounce, while U.S. gold futures eased 0.6% to $1,796.00.
