Spell Thunderstruck Slave Cuff

Spell Thunderstruck crystal cuff Silver version Could use a polishing up, I personally like it looking “worn”. The discoloring on the inside is also rough-ish feeling… not sure if it chipped or peeled or what the story is there. Chains are all attached firmly. Spell stamp visible on the inside. Couldn’t see a sterling stamp anywhere so I’m not sure about that.
