She’s a real gem.

Cops busted a jeweler to the stars who allegedly wanted to brawl over a precious Greenwich Village parking spot, authorities said today.

Dawnella Joie Jager, 42, and Meng Dong, 29, both came to the spot at 108 Christopher St. this past Thursday night, police said.

They argued over it before Jager, who was backing into the spot, jumped out of her car, opened the door of Dong’s vehicle and punched him in the chest, law enforcement sources said.

She then allegedly took at swing at Dong, who lives in Queens, with her umbrella, allegedly causing cuts and bruises to his arms and hands, sources said.

Responding officers booked Jager for misdemeanor assault.

Jager, who is originally from Los Angeles, claims her jewels have been worn by celebs such as Heather Graham, Kim Kardashian and High School Musical star Vanessa Hudgens.

Jager, a former actress, described herself on her Facebook page as a “quintessential taco and beach-loving free-spirited California girl living (and freezing my ass off) in NYC.”

On Facebook, she also wrote that she likes “unicorns, rainbows, puppies and kittens. oh, and pink.”

Ironically, when it came to her “political views” Jager, wrote, “Can’t we all just get along?”
