So are you saying at this time, no one should buy a WhiteFlash or GOG GIA Excellent because they are unqualified to pick outstanding GiA excellents out of the bunch? That appears to be what you''re saying, because I never suggested in any way that ALL GIA excellents were acceptable. I said the specially selected ones by WF and GOG are worthy of being considered as well as AGS0. So if I''m wrong, there are a few of us who need to return stones to WF and GOG.Date: 9/18/2006 3:15:57 PM

Both WF and GOG identify GIA Excellents which are Ideal cut, so that is not an issue at all in the situation where people are being steered only to AGS0. However, staff from either store can say an SI2 is eyeclean to them, but until you see it yourself, you do not know whether it will truly be eyeclean for YOU. It can expensive and time consuming to send for stones and then have to return them.
So these two things are NOT the same.-----------

Respectfully, there are some very great differences here. Please consider that I am not trying to make anyone feel badly about their GIA Excellent Cut grade stone, nor do I intend to insult someone''s judgment in picking what their personal choices have been.
Marty, has statistically analyzed the results of how many GIA ex''s are issued as compared to AGS issued ones. I believe he has stated that his analysis shows that GIA will issue an ex cut grade 7 times more frequently than AGS will. While in the eye of a consumer, there maybe no difference, there IS a difference to us who are able to discern differences and that does affect the value of the stone. This may be an issue for some and not for others.
For those who have GIA ex''s the PGS software can issue a far more detailed analysis. Some of the GIA ex''s will cut grade as AGS 0 ''s - but I''d also say that some won''t. I have seen some ''signature'' stones that have AGS 0 cut grade reports, that are slightly less, than others. While the AGS cut grade system is ''tighter'' than what GIA does, it still leaves open some variance, and carefully examined it shows at least to those qualified to discern the differences.
As I wrote above, AGS PGS isn''t yet ''perfect'', but at this time it is the best we have. Using that informational data, in comparison with other tests, it provides another level of information that is valuable to consumers when analyzed.
All of the technology is ''young''. I look forward to future development, and improvement which WILL come in time.
The really tough part is that unless a diamond''s proportions, quality of workmanship, are depart from the ''norm'' they still look ''beautiful''. Consumers should always keep in mind that ''beauty is not always something that we can analyze or predict as personal preferences, which are also many times relegated to BUDGET, is apparent.
I would offer that virtually none of the analysis equipment considers a beauty result. Some folks want contrast and white brilliance, others like broad flash of dispersion, other like the small rainbow colors and some wish that their diamond have more scintillation from across a room at a distance.
The PGS brings the playing field a tad more level. It can certainly help sort of the really ex cut grades from the wannabe cut grades.
As long as the analysis is well disclosed as to certainty, and any limitation or condition, it is useful, helpful and informative to consumers.
