No doubt the book is beautiful. The photographs and text are just enough for the eye-candy type book it was meant to be. My problem with it is that the title should have made it more clear that these rings are mostly 'artwear' and not jewelery like most of us expect. The book is intended for the experimental artists not for serious jewellers. There are *some* stunning examples of real jewelry and extremely creative and innovative styles but very few. The '500 brooches'book is the same. The cover and back plate are a little deceiving. Worth getting out of the library but not buying.
