I'm wondering if I've fallen in the Hearts on Fire sales pitch. I got a .463 G SI1 for $2500. I put it in a tension mounting and think it looks very nice. I realize I probably could of done better by getting a diamond off the internet, but I like having a store nearby and dealing with an acutal person. My question is what kind of value do the Hearts on Fire hold? Obviously the last thing the jeweler said was "you bought a very high quality stone" which I took with a grain of sand, cause I don't believe any opinion of a salesperson. Also, HoF are graded by AGS, not GIA - is that bad?
