Vintage Crown Rhinestone Pin. This large and lovely pin measures 1 3/4" long by 1 1/2" tall. All the rhinestones are prong set and sparkle like crazy. There are no missing or or discolored rhinestones. The pin mechanism work fine.
The back looked a bit tarnished and it cleaned up with a silver polishing cloth. However, a silver test showed that it is not sterling but some type of alloy with some silver content.
