SINGAPORE, Aug 8 (Reuters) - Gold tumbled to an eight-week trough in volatile trade on Friday, losing some of its shine as an alternative investment after the dollar jumped against the euro, prompting some investors to switch funds back into currencies.
But lower prices spurred buying from jewellers in India, the world's main consumer, and other countries in Asia. Platinum failed to sustain gains as fears of supply curbs following a one-day strike in main producer South Africa subsided.
Silver tumbled to its weakest since late January, tracking gold.
Gold <XAU=> hit a high of $873.50 an ounce before dropping back to $863.25/864.25 an ounce, down from $871.05/872.45 late in New York. The metal also hit an intraday low of $862.00 an ounce, an eight-week trough, on selling pressure from the rising dollar.
"It's very bearish. Oil prices are dropping, the dollar is up and platinum is very bad. People are scared about the volatile market," said Ronald Leung, director of Gold Dealers in Hong Kong.
Gold has dropped more than 15 percent in value since spiking to a record high of $1,030.80 hit in March.
The euro extended losses against a broadly stronger dollar to fall more than 1 percent as concerns about the region's growth outlook weighed on the European currency. [

"In the absence of commodity-type news, I think the market is probably going to be weaker. I think it's mainly dollar-dominated today," said Mark Pervan, an ANZ senior commodity analyst.
"I think around $850 would be a critical level," said Pervan, who pegged resistance at $900.
Spot platinum <XPT=> fell to $1,565.00/1,577.00 an ounce from $1,572.00/1,592.00 late in New York, having hit a high of $1,578.50 an ounce.
"As for platinum, $1,550 may be the next target. If you compare with Johnson Matthey's forecast, this is incredibly cheap," said Yukuji Sonoda, precious metals analyst at Daiichi Commodities.
Platinum prices have taken a dramatic turn since spiking to a record high at $2,290 an ounce in early March, losing much of their gains to profit taking and a slowing U.S. economy that threatens to slash demand for autocatalysts.
The current price was well below the target of $2,500 forecast in May by Johnson Matthey <JMAT.L>, the world's largest platinum refiner and distributor, citing output shortfalls and strong demand.
The bulk of the world's platinum is used by automakers in autocatalyst systems that scrub exhaust fumes of dangerous and environmentally damaging chemicals.
