Sorry crease, still not wild about the high price on that one, and definitely not for that IS.
Check with WF about their ES one that is a similar size but a couple of thousand cheaper (and it has fluoro which may actually help the color a bit) - I suspect it won't be eyeclean (looking at how long they have had the stone), but it is worth checking, and I like the IS better. You also would need to check about the vtn portion on that girdle. The diameter is basically the same as the one you posted. http://www.whiteflash.com/round_ideal_cut/Round-Ideal-Cut-cut-diamond-1204638.htm
Contact ID jewelry about the one I posted on your other thread - I think the rating of 'good' cut on the face page was a typo as that stone also has an AGS0 rating and is thousands cheaper for a higher grade in color too. Just check on eyecleanliness and ask him for an IS.
Also check into the JA AGS0 one on your other thread too - ask for an IS on that one and check eyeclean - it is also a couple of thousand cheaper for a higher color grade.
Darn. Check on the other two - I think they are still worth looking into. It would be a shame to pay that much over what others are going for and not have perfection for the extra $$.
You will find it - sometimes to get a big stone that is well cut it takes a while but in the end it will be worth it (and it sure will make you appreciate it every time you look at it!)
