Bookish Rings

I found some wonderfully bookish rings over on Etsy. I love the bookshelf above made in sterling silver by the XanneFran shop. The rings are hand made and made to order. What fun. She also has an open book ring.

I also love this ancient book ring from Coryographies on Etsy. The book is made of polymer clay and paint. It's done beautifully. They also make a Penguin book cover ring that is to die for...

I love this book vignette ring from YummykupeShop. So creative. 

Which one if your favorite?
