An NYPD cop was arrested in Staten Island for hawking jewelry she stole from her boyfriend’s mother, law enforcement sources said Friday.

Stacey Staniland, 29, twice broke into the home on Egbert Avenue in Elm Park, once on Nov. 25 and again on Dec. 1, and swiped necklaces, bracelets, and other jewelry, according to a criminal court complaint.

The sticky fingered cop took the jewels to Cash Depot on Morningstar Road near Richmond Avenue and pawned it for cash, the complaint states.

Staniland was also seen trading jewelry for cash on May 8, the document states.

The cop, also from Staten Island, was charged with burglary, grand larceny, and criminal possession of stolen property.
