I haven't seen this in real life or on screen but this ring looks rather odd to me - as if it is the framework for inserts of a contrasting stone like MOP or onyx, or possibly both.
Ah no I've seen that ring before. Its open. So on the finger it looks like two fine eek bands that are quite wide apart and joined with a vertical line of eek.
I've said before, it's a bugbear of mine that they don't show rings on the hand. Every show has a model wearing the rings so why not a photo for their webpage...
.... Hang on! Silly me. We are talking about Q's website here!
