This is a really cool vintage counter-culture, hippy ring, made by an artisan jeweler. It has some great detail and craftsmanship, and features a very large genuine carnelian stone in the center. There are 8 bell-like charms hanging on the 4 corners. It would likely fit a size 6 or 7 finger, and is unsigned. The carnelian setting measures roughly 1 1/4 inches. It will arrive in a nice box for your safekeeping.
