Brushed gold will show a satin finish.

The photo above is not the best photo, but it gives you the idea.
Trinkette is exactly on target with her comments. A brushed finish is MORE likely to show scratches as compared to a bright polished finish
I've always thought David's pictures were spot on. VERY hard to photograph diamonds.
I think for the most part, WG/Rose/YG are the same in price assuming if it's all 14k or 18k? I think 18k is general more expensive..

18 karat gold will be more expensive than 14 karat gold, regardless of color.
Generally speaking, the color of gold being white or yellow does not have a large impact on the price. However with pink gold, we have found prices slightly higher than with yellow or white gold. This could because we're very particular about the pink gold and how to get the right color
