Officers were called to Tindall's Diamonds and Jewelry at 1003 Washington Boulevard around 6:00 p.m. Wednesday.
Sources tell Action News that two men and two women entered the store, separated, then worked to distract the employees.
One of the suspects then reached into a case and grabbed an unspecified amount of loose diamonds.
The group fled the store and took off in a black Audi with Pennsylvania tags.
Action News was on the scene as a large number of police officers conducted the investigation inside the store.
No one was hurt during the theft.
