Silver also plunged by Rs 1,300 to Rs 46,000 per kg on poor offtake by jewellery fabricators and industrial units.
Traders said reduced offtake by stockists and jewellery fabricators on subdued demand mainly kept pressure on precious metals here.
Weak global trend as a rally in equities, that cut demand for the metal as an alternative investment, further fuelled the downtrend, they said.
Gold in Singapore, which normally sets price trend on the domestic front, dropped by 0.4 per cent to USD 1,270.97 an ounce and silver by one per cent to USD 20.22 an ounce, the lowest since August 9.
