I found this at a church rummage sale. Along with gold chain. The 18kt gold backing the ,, medallion is attached two is in fact 18kt gold. When tested by machine it showed between 14kt and 18kt gold. Im hoping for more info on the medallion. Thank you ahead of time for your help
My first thought was the medallion has come from something else and has recently been mounted on the pendant.
By 'recent', I mean the medallion looks to be older than the mount, it may have been soldered together sometime in the last 30 years.
