From the tip of his beak to the back of his head, the Raven is about 43 mm long (1-3/4 inches). It's hollowed out under the head, so it's not too heavy, but it's quite a substantial piece. It can easily be worn on the ring finger of either hand, but y'know what looks cool? Wear it on a middle finger - or index finger - or even your thumb!
A lot of people NAME their rings! If you do, I'd love to hear what it is! Size your finger, as if buying a smaller ring - the hollow under the head allows your finger to expand, so you don't need to order a larger size than usual. I can make one for you in just about any size. Available: 5-6-7-8-9-10-11-12-13, plus half sizes.
