Gold prices rose by 55 rupees to touch fresh all-time high of 29,750 rupees per 10 grams in the bullion market in Delhi today. The rise in on the back of sustained buying from stockists and investors even though the metal declined in global markets. Silver, on the other hand, remained under selling pressure and declined by 300 rupees to 55,900 rupees per kg on lack of buying support. Traders said sustained buying by stockists and investors along with a weakening rupee pushed the gold's prices to scale new height. In London, gold fell by 0.4 per cent to 1,628.90 USdollars an ounce.
