NEW YORK/LONDON, May 18 (Reuters) - Gold prices ended unchanged on Tuesday, supported by safe-haven buying due to volatility in the euro market.
After trading mostly lower in early activity due to hopes that a European rescue to resolve the region's debt crisis would work, gold rebounded as the euro tumbled to a four-year low at under $1.22 per ounce.
Platinum and silver, which have a strong industrial demand component, rebounded after the previous session's sharp declines. Worries that austerity steps in the euro zone could hamper growth, however, pressured prices, analysts said.
Investors' interest in the metal remained piqued by the prospect of sovereign debt risks spreading beyond the euro zone.
"The fact that Greece has actually received some of the aid package has probably taken some heat out of the market, but we still have to see if the aid is a cure, or just a temporary sticking plaster (bandage)," said Societe Generale analyst David Wilson.
Spot gold <XAU=> was at $1,220.85 an ounce at 3:25 p.m. EDT (1925 GMT), against $1,223.00 late in New York on Monday.
U.S. gold futures for June delivery <GCM0> on the COMEX division of the NYMEX settled down $13.50 at $1,214.60 an ounce.
COMEX open interest rose almost 15,000 lots to an all-time high above 600,000 lots as of May 17, indicating rising volatility as prices held near record highs, traders said. <NYMMTLFUT/VOI>
Contagion fears about Greece's debt crisis drove gold to a record $1,248.95 an ounce last week and knocked other assets lower.
Independent investor Dennis Gartman said he was abandoning his long-held strategy of buying gold relative to non-U.S. currencies, such as the euro, due to rising volatility in the metal and currency markets. [

Investment demand for gold remained high, with holdings of the world's largest gold-backed exchange-traded fund, New York's SPDR Gold Trust, rising just over three tonnes on Monday to a record 1,217.108 tonnes.
