A couple of years ago, I reported on a story about a man who bought a purple pearl brooch at a sale thinking it was costume jewelry and found himself with a piece worth around $250,000. A Florida man recently found another rare purple pearl this week and all he had to do was order a steamed clams. George Brock and his wife, Leslie found the pearl while eating at Dave's Last Resort & Raw Bar. Their pearl isn't quite as big the one in the brooch but it could be worth thousands. The couple will have it appraised and then decide if they will sell it.
