NEW YORK/LONDON, July 31 (Reuters) - Gold ended higher on Thursday, having rallied 2 percent earlier in the session as the dollar dropped after weaker-than-expected U.S. jobs data, but oil weakness crimped bullion's gains.
Gold <XAU=> was at $913.45/914.65 by New York's last quote at 2:45 p.m. EDT (1845 GMT), compared with $907.20/908.40 an ounce late in New York on Wednesday.
Traders are awaiting key U.S. data, including U.S. non-farm payrolls numbers due on Friday morning, to set fresh direction to trade.
"The employment numbers are always the biggest piece of data out," HSBC analyst James Steel said. "That is going to be a determining factor tomorrow."
Gold prices rallied sharply earlier in the session as the dollar slipped after data showed an unexpected rise in U.S. weekly jobless claims, and as second-quarter GDP numbers came in softer than expected. [
]Bullion also boosted after European Central Bank sources told Reuters on Wednesday that the ECB will raise interest rates again if inflation keeps rising, despite faltering economic growth. [
]Bill O'Neill, managing partner of LOGIC Advisors in New Jersey, said that a slew of U.S. and European inflation data, including the core inflation reading in the U.S. GDP report, showed that inflation was still rising fast.
The precious metal touched a session high of $925.20 as investors bought into gold as an alternative to the dollar.
However, a sharp drop in oil prices to below $125 a barrel knocked gold from its earlier highs. Bullion typically moves in line with crude, as it is often bought as a hedge against oil-led inflation.
"The only reason gold is off the high is because of this sudden weakness in oil," noted Steel.
U.S. gold futures for December delivery <GCZ8> settled up $10.40, or 1.1 percent, at $922.70 an ounce on the COMEX division of New York Mercantile Exchange.
The Chicago Board Options Exchange, the largest U.S. options market, said on Thursday that it will roll out a new benchmark, the CBOE Gold Volatility Index <.GVZ>, which tracks projected volatility in gold prices. [

Platinum and palladium, both largely used by carmakers as a component in autocatalysts, ticked up on Thursday, having slipped in gold's wake in the previous session.
Spot platinum <XPT=> ended higher at $1,750.50/1,770.50 an ounce, up from $1,725.00/1,745.00 late in New York on Wednesday.
"The slump in platinum has brought out the buyers and the metal has found support in the low $1700s/oz," said UBS analyst John Reade in a note.
"We believe that platinum is now attractively priced and that investors looking to buy good amounts should scale into platinum at current levels."
Spot palladium <XPD=> finished at $378.00/386.00 an ounce, up from $371.50/379.50 late in New York. Silver <XAG=> ended higher at $17.71/17.77 an ounce from its previous finish of $17.50/17.56.
The iShares Silver Trust <SLV.A>, the largest physically backed silver exchange-traded fund traded in New York, said its holdings rose above 200 million ounces for the first time on July 29. [
