One Lonely Earring

I found this lonely earring on the Track 1 platform at Suburban Station this morning at 8:50...right after the R5 arrived. It looks like a nice one and has a purity stamp on it (I think from Tiffany's). I wonder if there's another lonely earring out there in Philadelphia that would like to be matched up with this one. (This is a bit of an experiment...what are the odds that this earring gets back to its owner? Probably pretty small.) The oval silver earring has a gold hoop inside. Anyone know a person who lost this little gem? Leave a comment below. I'd love to return it.
