This is a high-poly silver ring I modeled after a photo of a similar ring. I very much like the idea and simplicity behind its design. It's rendered with Luxrender. The font I used for the texture is Tengwar Annatar by Johan Winge and is freely available, but not included.
Awesome design! I simplified and optimized your design for 3D printing. You can see a physical copy of your ring on thingiverse: http://www.thingiverse.com/thing:131169
