I don't know anything about this piece at all. Its signed the Vatican library collection, it's a heavy cross enameled on top with a clear enamel then has a pretty design under it. The sides have a nice design too, it has a long gold rope chain with lobster clasp. This was in a boxed lot and I did research for pricing but know nothing else about it. It's in excellent condition! chain is about 32" long cross is - 2.75" tall by 1.5" wide at widest. heavier cross.
