I wasn't so sure about this at first. But the more I see it, the more I like it. Loads of book-themed jewelry is so twee (which I happen to enjoy) but for those wanting something with a modern edge, this is a good choice.
Do you think it looks also looks a bit like an book inspired knuckle-duster?
This silver book ring is £55.45 and can be bought from Metalnat's store on etsy.
