* Miners, banks, luxury stocks lead declines

* U.S. core consumer prices slow sharply in August

* Pandora up after boosting earnings target, buyback

* JD Sports jumps after profit surge

Sept 14 (Reuters) - European stocks ended flat on Tuesday, with miners, banks and luxury stocks leading declines as optimism over cooling U.S. inflation growth in August proved to be short-lived.

The region-wide STOXX 600 index inched 0.01% lower, with the basic resources sector index dropping 1.9% and banks sliding 1.1%.

"Having got off to a positive start yesterday, today's price action looks set to follow the pattern of last week, where after a similar Monday rally, sentiment deteriorated as concerns about profit margins in the face of rising prices saw certain sectors come under further pressure," said Michael Hewson, chief market analyst at CMC Markets UK.

Luxury stocks, including LVMH, Kering, Richemont and Burberry, fell between 1.9% and 3%, tracking moves in Asia on concerns about the spread of COVID-19 cases in China.

"Ongoing China coronavirus concerns and lockdowns in several cities in Fujian are not helping sentiment," said Mark Taylor, sales trader at Mirabaud Securities.

Home to many luxury names, France's CAC 40 fell 0.4%, while the UK's miner-heavy FTSE 100 shed 0.5%.

Still, many strategists expect European equities to outperform this year due to relatively high rate of vaccinations and catch-up trade in cheaper segments of the market such as banks and energy.

Data earlier in the day showed underlying U.S. consumer prices increased at their slowest pace in six months in August, suggesting that inflation had probably peaked, though it could remain high for a while amid persistent supply constraints.

The report supported sentiment for a brief while in midday trading as investors were hopeful that the U.S. Federal Reserve would likely delay its announcement of cutting back monetary stimulus.

"While we initially saw markets spike on the prospect of a more patient Federal Reserve, we have since seen traders realize that today's data is unlikely to push the Fed to change course," said Joshua Mahony, senior market analyst at IG.

Pandora, the world's largest jewelry maker, rose 6.8% after it boosted its earnings target for the coming years and lifted its share buyback plan.

JD Sports Fashion jumped 9.7% after it reported a record first-half profit as lockdowns eased and people visited its shops in Britain.

Dutch specialty chemicals maker DSM hit a record high after it said it was weighing the sale of its materials division.
