A Diamond District jewelry peddler is accused of acting as the lookout in a $2 million gem heist from a tony Manhattan antique center, police sources said yesterday.

Cops nailed suspect Draze Jovanoski, 51, of The Bronx, via surveillance video and by tracing repeated cellphone calls he allegedly made during the robbery at the Flatiron District site to a nearby communications tower, placing him in the area at the time, the sources said.

Sources say Jovanoski and two cohorts busted into the front door of Showplace Antique and Design Center before the accomplices cut a hole through a fire door to gain access to at least four shops and stole hundreds of pieces of jewelry.
