Rook Cut Rock Total Posts: 294 Last Post: 2/9/2004 Member Since: 10/4/2002	I have found a diamond and everything looks good about it numbers wise. There are two concerns I have though. 1)Girdle is Thin to Thick 2)GIA has additional comments of "Clouds are not shown..Surface graining not shown" 1)Is this anything I need to be concerned about? I am still waiting on the sarin to find out how thin and how thick the girdle is, but what is a tolerable variation between the thinest and thickest points? What effect will this have on performance and durablity of the diamond? 2)I read somewhere that these types of comments are put there by the GIA just to be precise, and they are listed as comments because they do not effect the performance or duability or anything really about the diamond! Any truth there? Thanks Rook Hope this helps! Rook.

There are not very many pears with vg sym, and vg polish? Is it worth holding out for one? If I can not visibly see any sym/pol defects on a g/g stone is that fine? Hope this helps! Rook.

barry Cut Rock Total Posts: 440 Last Post: 12/1/2003 Member Since: 3/22/2001	The answer to your Q-#2 is Yes. It's put there for informational purposes. You will have to view the diamond very carefully through 10X magnification to see 'clouds' and 'graining'. Otherwise, the diamond is definitely eye-clean. As far as girdles are concerned, nothing to worry about with 'thin' as it usually refers to one/or a few specific spots on the girdle. This will not affect the durability of the stone. You should be concerned with a girdle that is listed as 'extremely thin' as this may mask an imperfection,fault line, or cutter's "swindling" the stone that may rear up and bite you in the rear-end down the line. 'Extremly thin' girdles are also problematic in fancies that have "points", e.g., Marquises, Pears, and Princess Cuts. Note whether the 'extremely thin' lies at or near the point; if it does you're asking for trouble. These areas are very sensitive and girdles should be 'thin to medium' at the very least.

I've seen many fancies with these Polish/Symmetry grades that are absolute duds in terms of light return. You can have G/G Polish-Symmetry and if the Crown/ Pavilion facets are positioned correctly against each other, will yield a high light-output visually very appealing diamond.

Rook Cut Rock Total Posts: 294 Last Post: 2/9/2004 Member Since: 10/4/2002	Barry, Thanks for your replies: I have been staying away from extremelys and verys in the girdle range. I have actually been looking for a thin to med, or a med to thick. I was just not sure if the larger variance in having a thin to thick was going to give me possible problems. Also I have found a couple of pears that look great but have g/g pol/sym. I guess I am just not well informed about pol/sym. I think I understand what constitutes good vs very good pol/sym, just not what the difference it will make. For example if you had two diamonds, exactly the same in every regard except one had g/g and the other had vg/vg, would it really matter? Beyond being able to tell looking through a loop? Hope this helps! Rook.

Properly done, you will "see" more light coming at you from the Crown and Table. You can have two diamonds with very similar specs 'look' quite different. Keep looking and comparing.
