• Gold hits 1-week high on rising euro versus dollar;
• Nikkei up on hopes over economic proposals;
• Oil up to above $44 a barrel;
• Investors await U.S. weekly jobless claims.

SINGAPORE, Dec 11 (Reuters) - Gold bounced from lows to hit a 1-week high on Thursday, a day after posting its biggest daily percentage gain in almost three weeks, as the euro firmed against the dollar and oil advanced on the prospects of output cuts.

Investors' appetite for risky assets was somewhat restored after bullion regained $800 for the first time since early December on firm U.S. equities, rising oil and broad-based commodity gains, dealers said.

Gold was trading at $813.40 an ounce, up $3.50 from New York's notional close on Wednesday, when it rose more than 4 percent, its biggest daily percentage gain since Nov. 21. Gold was 19 percent above a 13-month low around $680 hit in October.

"There's firmness of the euro against the dollar and oil is also a bit higher. That's why gold is up," said Ellison Chu, manager of precious metals at Standard Bank Asia in Hong Kong.

But jewellery makers were on the sidelines after prices rebounded and physical trading had also slowed as the end of the year approached, Chu said.

"There's no buying at this level. Nothing."

Gold had hit an intraday low of $801.60 on Thursday before the equity markets reversed losses and helped push up prices to as high as $815.45 -- its strongest since Dec. 1.

Oil rose further to around $44 a barrel on signs that Saudi Arabia had slashed supplies substantially to major customers for January ahead of an OPEC meeting next week that is expected to agree to more output cuts.

On Wednesday, the Reuters-Jefferies CRB Index, a global commodities benchmark, rose around 3 percent, after having settled down almost 2 percent on Tuesday.

"We've obviously seen the commodities rally again, a generic rally. Gold is probably the most attractive of the current commodities from an investor's standpoint," said Darren Heathcote of Investec Australia in Sydney.

"Given that we are having relative stability in the stock markets, I would suggest it's certainly underpinned. With the possibility of production cuts in oil, we've got potentially more reasons to be buying gold," he said.

Gold could find support around the 10-day moving average around $782, said dealers, with resistance seen at around $822 -- an intraday high hit in late November.

Fears of rising energy costs helped propel gold to a record of $1,030.80 in March before it slipped after oil changed course, and recently due to a sell-off in equities, which forced investors to sell bullion to cover margin calls.

Some investors maybe careful about taking large positions ahead of the release of U.S. weekly jobless claims later in the day, which could erase gains in oil and stock markets if it unveils bad numbers.

The Nikkei rose 0.7 percent on Thursday on hopes that global stimulus measures would prop up the economy, offset a stronger yen as well as worries whether a U.S. auto bailout would be passed by the Senate.

The euro rose as high as $1.3115, a one-month high.

Platinum traded at $829.00 an ounce, up $7.00 from New York notional close but it failed to sustain early gains to $830 due to uncertainty over U.S. auto bailout package.

New York gold futures added $5.7 an ounce to $814.5 in electronic trade.
