This is a great vintage bracelet from the 50s or 60s. All bracelets have a slight different patina to them.
The bracelets are 14K Gold Plated and there are two sizes available: Small/Medium and Medium/Large.
They have been sitting around in an old warehouse and recently discovered! They are very well made and the oval front is actually the hook. They are about 15mm tall so they can be seen yet they aren't huge either.
