This image was created with Blender 2.68 with some minor post processing and color correction in Gimp.
I created it as part of the weekend challenges here:

This is for weekend challenge number 544 with the theme: My Next Life
It might be a little difficult to tell, but the text on the inside of the rings is actually modeled and not an image texture. I followed the basic procedure used in this tutorial here:

I then used a curve modifier to make it in to a ring shape and after applying the modifier, I finished modeling the exterior part of the ring.
Any comments and critique is welcome
