OMC, I would have "tagged" you on that post if I could have- your response stated just what I was thinking, too! Yes, it's not possible to tell from just the one photo, but in my VERY undereducated opinion, a stone that large, white and eye-clean has got to be lacking in something to be at that price point, and I didn't think it was all that "lively", either.
NYH, have you done any serious comparison shopping? I know it's easy for those of us who love DBL and this forum to plug David's merchandise, but, honestly, THERE'S A REASON. You have nothing to lose by giving them a call and finding out what they can come up with for you, so at least you'd have a better idea of what you could get for your money? I can tell you from personal experience that the photos and videos on the DBL website will really tell you what you're getting in a stone, in case you're worried about purchasing sight-unseen. (I am in CO, and it literally took me less effort to get my ER from DBL than it did to buy one locally, probably for twice the price!)
Either way, I hope you stick around! We always love to talk sparkles around here, regardless of where they're from. Keep us posted!
