.. but now, I am not sure what it is. Here are the pics of the front and back. It measures 1.5" by 1.25" by .18 inches thick, and the stem appears to be broken off. Kind of a neat piece, but have no idea what it is.
I had it cleaned tested at a well respected jewelry store, and they said it was <10kt. gold. I am not real sure what exactly the other metals might be, but gold is gold I guess.
