Victorian watch fob chain clip

Late Victorian/Edwardian jumbo ring snap. This is from an antique watch chain. These pieces are incredibly collectible and on trend now! Dog clips, T bars , fobs, and ring clips. I can’t see any markings by simply looking. It may be hallmarked. The gold is a beautiful warm yellow. I have not tested this. So I’m listing it as old gold fill. Spring works great. Georgian-Victorian-Edwardian….all of these romantic eras look wonderful mixed.
