This heavy chain is in good condition. It is a box chain and secure with a hook over link closure. We are of the opinion the hook closure is a later addition.
The original sterling silver link is still in place as shown. It is marked 925 and EBM.
The chain has some age to it and there is tarnish in the depths of the links.
The chain is 4.4mm wide and measures 420mm long. It weighs 44.1gms.
