For Juan...May be of help

I ran across this while surfing. This is the closest ring to your original description that I have seen. Sorry you missed out on the other ring. Maybe you can call these people to get a quote for customizing a ring for you. They''d probably have to take the bars off of the sides for you and leave the center unset (and make it larger) to accomodate your stone.
