The incident occurred at 4:15 p.m. on Friday at the Zales store located at the mall.
Store employees tell police that three males entered the store and separated once inside, speaking to different employees about jewelry.
None of the men made a purchase before leaving the store.
Shortly after the suspects left, employees discovered two diamond rings, which were valued at approximately $15,000, missing from a display cabinet.
The first suspect is described as a black male with a dark complexion, between 35 and 45 years of age, approximately 6'2" with a thin build, with salt and pepper hair and a beard.
The second suspect is described as a black male between 50 and 60 years of age, approximately 5'11" tall, with white hair and a beard.
The third suspect is described as a black male, 60 years of age, approximately 5'6" tall, with an average build, salt and pepper hair and was missing a few front teeth. Police say he carried a cigar and had a distinctive necklace with a handgun shaped charm containing diamonds.
Police have released sketches of the first two suspects hoping someone can help investigators identity the men.
