I probably could have been a lot more detailed, but then I would have bored myself to death! Thanks!

Flawlessly certified?? (Reply to this comment)
by Certified
I like what you have said, but would like to elaborate on a couple of categories.
Cut: Not only is this the shape of the diamond but also the interactions of facet symmetry, quality of polish and angles chosen. This was mentioned somewhat but I just wanted to re-emphasize that the angles chosen are critical. Most cut grades are based against the Tolkowski formula (now refered to as the Ideal cut).
53% to 57% table
34.5 degree crown angle
medium to slightly thick girdle
43% pavilion depth
a reasonable culet (none to small, nothing chipped or extreme)
No Flawless? There is a grade of flawless given by GIA and they do exist. A flawless clarity grade is given to a diamond with no inclusions or blemishes at 10 power. There are three exceptions: internal graining which is colorless and not visible, a natural (an area of the original crystal skin) confined to the thickness of the girdle and a small extra facet on the pavilion which is not visible face up and does not distort the outline.
Just for the record, GIA does not certify anyone or any thing. They only offer diplomas for their graduates and their lab, GTL (Gem Trade Lab) has diamond quality analysis reports and gem id reports. "Certified" implies a warranty or guaranty of performance or an endorsement by GIA. This is why GIA forbids the use of "Certified" in conjunction with their name. The jewelry trade inadvertantly uses this word and in some cases individuals use it to make themselves seem qualified to be better due to an association with GIA. Sometimes a diamond is advertised to be "GIA Certified". Realize the GIA GTL will grade any quality of diamond, so even an ultra dog stone can have a GIA report. Beware, a GIA report doesn't make the stone better, it just reports the quality of the stone.
Thanks, I'm off my soap box now.
Arthur
P.S. I still prefer to buy diamonds with a GIA report, I just like the better quality ones.
