I'd really appreciate thoughts on options for a 3/4 ct (more or less) cushion diamond. Don't think I want to spring for something like a BG Signature cushion (though I appreciate the precise cut), but still want great quality and decent value. Some examples I found below to compare. Would these stones look much different from each other if I was lucky enough to be in a room with all 3?
