Besides, subdued demand from jewellers and retailers following end of festive season and shifting of funds towards soaring equity markets, weighed on prices of the precious metal.
Silver followed suit and recorded a sharp fall of Rs 1,700 to Rs 36,150 per kg on poor offtake by industrial units and coin makers.
Bullion merchants said a weak trend in global markets as US economic data and a stronger dollar eroded demand mainly put pressure on the precious metal prices.
Further, a subdued trend at the domestic markets as demand dried up due to end of festive season, dampened sentiments, they added.
