Beautiful bracelet is in very good pre-owned antique condition with a lovely patina and gentle wear noted.

There is a little room for about a quarter inch expansion with a cross over closure that slides at the wire wraps. There is a beautiful Chinese hallmark that is slightly worn. See pictures 8-9.
