Jewelry Heist at Orlando Bloom's Place

Burglars apparently knew what we didn't -- Orlando Bloom had hundreds of thousands of dollars worth of jewelry in his Hollywood Hills home. Notice the past tense, because we've learned burglars made off with the bling Monday night.

Law enforcement tells us the thieves entered Bloom's house through a window and made off with roughly $500,000 in jewelry -- including two very expensive watches.

Cops fingerprinted and photographed the scene. So far no suspects.

Bloom was in NYC at the time.

UPDATE: Law enforcement sources tell us it does not look like "a typical burglary." They will not say if it looks like an inside job.
