I have HW wedding jewelry which is just SO MUCH better value that those really overpriced and overhyped stones at Tiffany. 40K will get you something around 3 carats for a solitaire on platinum. I have never looked at the multi-stone rings though.
3 carats for 40K? Say it ain't so. That sounds actually reasonable to me, but then again I really know nothing about diamonds and how they're priced. I wonder what it would cost for the same stone from an independent broker?
