I know Good Old Gold and Brian Gavin Diamonds have terrific reputations among PS members for fancy diamonds and ovals in particular. Given that ovals really need to be seen to ensure they are good performers ... would you assume any oval that GOG or Brian Gavin selects and lists for sale is going to be a pretty good one compared to other ovals available for purchase? Or are there going to be some duds sold by GOG and BG, too?
