That's quite a ring. I remember reading a post by someone back in 2007 who wanted to buy his GF a 3-carat stone and drop it in this setting. He was going into debt , if I recall, in order to buy his dream girl her dream ring.
I think I may have priced that setting and it was around $8K at the time - does that sound right? WISH I had pictures of that puppy!
ETA: I just saw the setting on Pearlman's site. Currently $6K. I was thinking of the one with diamond encrusted prongs, which is even more than $8K now.
