A band of thieves distracted employees at a jewelry store at the Exton Square Mall on Friday, then made off with two diamond rings worth approximately $15,000, West Whiteland Township police said.

Three of the four suspects entered the Zales store together around 4:15 p.m., then separated and looked at jewelry with different employees, police said.

"Two of the subjects were there dealing with one of the employees," said Detective Scott Pezick. "They were asking them different questions. At one point, the employee had to go in the back room, so we don't know if they reached around the display case with the key and took the two rings."

The employees noticed the rings were missing once the men had left, Pezick said.

The suspects were black males, police said. They described one as 35 to 45 years old, approximately 6-foot-2 and thin with salt-and-pepper hair and a beard. A second suspect was between 50 and 60 years old, approximately 5 feet 11 inches tall with white hair and a beard.

The third suspect was about 60 years old, 5 feet 6 inches tall with salt-and- pepper hair and missing front teeth. The police said he was carrying a cigar and wore a necklace with a handgun-shaped diamond charm.

A description was not given for the fourth suspect. Pezick said he acted as a lookout.
