However, firmness in base metals at the London Metal Exchange (LME) limited the fall.
At the Multi Commodity Exchange, nickel for delivery July month shed Rs 4.10 or 0.64 per cent to Rs 632.80 per kg in a business turnover of 624 lots.
The metal for delivery in current month shed Rs 4.40 or 0.70 per cent to trade at Rs 625.70 per kg in 1,659 lots.
Market analysts said the fall in nickel prices was mostly in tune with a weak trend at the domestic spot markets due to muted demand from alloy-makers, but a firm trend in base metals at the LME, restricted losses.
