Wow! These look awesome!

You should fix that with the inner
engravement being the wrong way
round (are you using bump-maps,
or CSG?).

Aside of that, how about using a slighty
irregular heightfield for the wood?

And regarding focal-blur: make the
aperture a nuance smaller, so that the ring
itself antialiased at most, but not blurred.
Move the camera away a little, and add
some stuff, like pots and cups and such,
in fore- and background. Use radiosity
to light that, but keep a soft spotlight on
the ring, to make it the center of attraction.

I often tend to make single objects and
showcase them in my scenes, but realism
is added with more objects around it. It
would also add to the reflections of the
ring.
