My initial thoughts on spending about $14-15000 for a 1.5 carat stone was to get a diamond in the D-E range and VS2 clarity, with a cut that was termed ideal or within ideal range, and a GIA cert. Should I look to move up in cut to a hearts and arrows or other branded cut, and if so, where should I cut back when buying over the internet? I would think maybe color and stay at a VS2 to be safe? I would like to get the best diamond I can for that price range over 1.5 carat. Any professional or novice opinions will be greatly appreciated.
