What is surface graining, and what are the price implications? Does it affect a diamond's cut, clarity or potentially both? Do Gia/Ags differ in what they thinkg of it? Does it affect brilliance, and if so how much? A diamond I bought has 'surface graining not shown' on the comments section, and I can't for the life of me *see* anything under 10x magnification.

"Surface graining" is something that is already factored into your diamonds clarity grade, and unless you are concerned over the current clarity grade, is basically not something you should be alarmed worried about.
What it is, is a ridge or group of ridges that are evident only from a certain angle, and of course under very high magnification. Think of trying to find a fingerprint on a glossy wood table, you have to tilt your head just so and have the light just right to see it. They don't plot it on the chart for that reason, that its only visible in a very limited viewing fashion, and if you drew it, it would of course appear like its a much bigger deal than in fact it is.
I don't think it would affect brilliance, and again, its already factored into your diamonds clarity grade, so I would not worry about it :-)
Hope that helps!
