TOKYO, Sept 5 (Reuters) - Gold edged down near $790 an ounce on Friday on the dollar's strength against the euro, as well as weaker oil prices, but solid purchases by Asian investors provided support.
Investors were also shaken by sharp falls in equities, prompting them to shift to dollars while pulling out funds from risky assets, including precious metals, but Asian bargain hunters were detected buying gold on dips.
"Gold started lower in Asia, falling near $790, but around the level we are seeing a big amount of physical gold buying from Asian players," said Yuichi Ikemizu, managing director at Standard Bank in Tokyo.
By 0300 GMT, spot gold <XAU=> was at $794.10/795.10 per ounce, down from $796.15/797.75 late in New York on Thursday. It dropped as far as $790.35 on Friday.
COMEX gold futures extended losses in Asia after settling down $5 in New York the previous day. The most active December contract <GCZ8> was trading at $798.5, down $4.7 or 0.6 percent from the New York settlement.
Cash gold fell as low as $789.05 on Wednesday, its weakest in two weeks and near its nine-month low around $773 hit in mid-August.
Indian buyers, the world's largest consumer, were detected to have bought in large volumes on price dips ahead of the peak festive season in October.
Investment bank UBS, one of the largest gold dealers, said that over the last two weeks, it had seen its strongest physical sales in 20 years.
But market participants were keen to see if further bargain hunting would emerge in the physical market.
Gold prices have been put under pressure, slipping about 5 percent over the past week, reflecting the strength of the dollar and plunges in oil prices.
The dollar rose against the euro <EUR=> after U.S. service sector data came in stronger than forecast, then extended its gains after European Central Bank President Jean-Claude Trichet said the euro zone was in a period of weak economic activity.
Oil prices were little changed near $108 on Friday after falling nearly 8 percent this week. [
]"Investors are extremely careful about taking new risk positions, including oil and commodities, while funds are shifting into the dollar," said Tatsuo Kageyama, a market analyst at Kanetsu Asset Management.
"It could take a while before the market can fully restore their confidence to shift back their positions into commodities," Kageyama said.
Tokyo platinum futures <0#JPL:> plunged more than 6 percent and the cash price <XPT=> fell over 2 percent as lingering concerns over demand for autocatalysts due to news of poor car sales in the United States prompted investment funds to sell.
Platinum was under speculative sales amid talk that carmakers were selling back their platinum holdings to the market due to poor sales.
U.S. auto sales results announced earlier in the week showed they fell 15.5 percent to 1.25 million units or to a seasonally adjusted, annualised rate of 13.72 million units in August.
This marks the 10th straight month of declining sales in the U.S. auto market -- the longest such downturn since the 2001 recession.
The benchmark contract for August 2009 delivery <0#JPL:> on the Tokyo Commodity Exchange fell by the daily 300 yen limit, or 6.1 percent, to 4,612 yen per gram.
Spot platinum <XPT=> dropped to $1,357.50/1,377.50 an ounce, down 2.4 percent from $1,391.50/1,411.50 in New York.
Palladium <XPD=> edged down to $280.00/288.00 an ounce from $281.50/289.50.
Silver <XAG=> fell to $12.70/12.76 an ounce from $12.74/12.80 late in New York.
