I was looking at HOF diamonds at a mall store this past week. The sales guy said they are "super ideal". He had one of those hearts and arrows viewer and asked to look at my stone. Mine is not exactly ideal cut, but he was suprised to see what he called "good arrows". Mine does score well on HCA (1.2) but is a cut class 2A according to AGS. My question is, does a true hearts and arrows like an HOF necessarily outperform all others? Is it worth the premium?
