I have been to some other websites and some people are accually buying engagement rings from Costco. I have my own not so optimistic opions after looking at their diamond rings. They accually have a ring for $53K in a yellow gold tiffany solitare (about $90 dollars for the setting) appraised by IGI. The link is below and I am curious on others opions.
