I'm just curious, when I read so much advice about buying diamonds online, sight-unseen, how do you know it's a beautiful diamond. The conventional wisdom seems to be that as long as it's an "ideal cut" (preferably a branded one) you can be assured it will be beautiful. Have any of you ever heard of the "eight-square" stage of diamond cutting? That's the seventeen facet stone as it comes from the blocker. It's not a pretty diamond, and yet the proportions are locked in at this point. It's the work of the brillianteerer, who puts the final 40 facets on the stone, that determines whether or not that stone will really pop. Beauty in a diamond is about much more than just proportions. Don't you think that if you're buying an object valued for its beauty, it's a good idea to see it?
