Thieves hit a pop-up jewelry shop at Gurney’s Resort and Spa on Labor Day weekend. A woman grabbed a hat from a display, the shopowner told police, and tossed it to a friend seated on a couch nearby; the two then left the premises, hat in hand. The owner, Hayley Denman, said it was a cheap hat, but that not long after, one of the women had returned and dropped a $5,400 diamond butterfly necklace into her purse before fleeing. The women, who will be charged with grand larceny if found, were last seen getting into an Uber.
