First, I would like to thank all who participate in this site, especially the folks at goodoldgold.com, dbof.com, and niceice.com.
This is mostly a question for Jonathan at goodoldgold, but I will open it up to the forum. (For those who haven''t seen his site, he has a wonderfully educational collection of pictures and diamond evaluations.)
I have been looking at Jonathan''s (goodoldgold.com) evaluations of Flanders cut diamonds. In every case where there is both a lab cert and his own evaluation, his eval shows the Length and Width at ~10% less than the lab cert. For instance, there is an educational 1.01 Ct Flanders with a GIA cert that says 6.36 x 6.34 mm. The Good Old Gold Analysis says the diamond is 5.78 x 5.79 mm. These dimensions are 9% smaller (0.57 & 0.56 mm).
Between the educational diamonds and the ones he has for sale, there are 5 PGS certs, 2 HRD certs, and 1 GIA cert.
I then looked at 2-3 dozen diamonds of different shapes (round, radiant, princess, emerald, regent) and never saw this--every one of his measurements matches up within a couple hundredths of a milimeter.
Can anyone explain what is going on here?
