Vintage Silver Cross Pendant with back that says “I’m not perfect just forgiven”

Love this piece! It is from an estate vintage lot, do not have any information on it or signed, it’s actually has a little weight to it but no way of testing it what it is made of, and you can attach to whatever you like with attached lobster clasp. Review all pictures, just a really different nice piece, thank you! *possibly JK but does not have tag*
