The Los Angeles Police Department on Thursday released video of the May 25 incident in hopes the public will recognize the suspects.
The incident started just before 4:30 p.m. when two men entered the jewelry store on Ventura Boulevard.
They pepper-sprayed the store owner and two customers, and then started using hammers to break glass displays.
One of the men also swung a hammer at the store owner, police said.
She then used her registered handgun to fire a single shot at the suspects.
Neither was hit, but that persuaded them to leave.
Video shows the men exiting the store, and having trouble with the door, then using a hammer to smash the glass. They slipped through the smashed glass to escape.
Police say no one was injured and no property was stolen.
Police described the first suspect as a white or Hispanic male, about 30 to 40 years old, with closely-shaved receding dark hair. He stands around 5 feet 7 inches tall and weighs around 150 pounds. He was wearing a blue, long sleeved button-down shirt, khaki pants, black tennis shoes, sunglasses and a watch on his left wrist.
The second suspect was described as a Hispanic male, about 40 to 50 years old with dark hair, mustache or goatee. He stands around 6 feet tall and weighs around 175 pounds. He was wearing gray pants, a white long-sleeved button-down shirt, bow tie, fedora, sunglasses and an earring in his left ear.
