NEW YORK (

TheStreet

) --

Gold prices rose Thursday as the U.S. dollar weakened against the euro.

Gold for December delivery added $5.50 to $1,770.60 an ounce at the Comex division of the New York Mercantile Exchange. The

gold price traded as high as $1,776.60 and as low as $1,760.20 an ounce, while the spot price was gaining $5.30, according to Kitco's gold index.

Standard & Poor's knocked down Spain's debt rating by two notches late Wednesday, but the euro was ignoring that news and investors continued to be optimistic about the possibility of a bailout for the country.

"The S&P announcement on Spain probably has a lot to do with the return to the rally tracks," Chuck Butler, president of world markets at EverBank, wrote Thursday in a note.

Silver prices for December delivery closed down 3 cents at $34.08 an ounce, while the

U.S. dollar index was lowering 0.41% to $79.77.

Gold was also shrugging off a week-long slump despite the better news that weekly jobless claims declined 30,000 for their biggest drop since July.

Investors have felt that good news in the labor market could signal a move by the

Federal Reserve

to end its open-ended, mortgage-backed securities purchasing program -- known as quantitative easing -- sooner rather than later. Despite last Friday's surprise drop in the unemployment rate and Thursday's decline in claims, gold is not seeing a charge toward the lower end of its current trading range.

"As discussed recently, I was cautious to short term bearish on gold based on overbought sentiment mainly. If it can hold 1753, it has a chance to spring back over 1800," David Banister, chief investment strategist at Active Trading Partners, wrote in an email.

The euro was climbing to $1.2934 against the greenback, ahead of its prior day close at $1.2876.
