Last month we brought you the story of a diner in South Florida who discovered a rare iridescent purple pearl in his steamed clams. Last week it happened again. Mike McHenry spit out a pearl while eating fried oysters in New Jersey. This pearl may not be as valuable as the purple pearl but it is rare. The owner of Russo's Ristorante says it's the first time in 33 years running a restaurant he's seen a pearl found in a plate of oysters.
