Hello guys! I was wondering if you guys could help me with some questions and assurances with a princess cut diamond. I'm just about ready to buy an engagement ring for my girlfriend and I don't want to mess this up since it's one of the most important purchases in a life!
I've been doing a lot of research and I think I comprehend a lot of stuff about the 4 C's but still have many questions. From my understanding, in a Princess Cut diamond you can't see the color of D-E-F diamonds and they recommend you stick in the G-H range? I also understand that GIA doesn't grade the cut of princess cuts. The ones I've been looking at are graded "very good" by the seller's standards.
When it comes to polish and symmetry, does that help it sparkle the higher grade you get? The one's I'm looking at are GIA - Excellent or AGSL- ID for polish and symmerty. Is it worth the money, or would it be better to drop down a grade to Very Good.
Also, the Ritani ring I'm looking at has sidestones with a minimum color of H. Say I found a nice diamond with a color of DEF or G, would it look out of place having a better color then the sidestones?
Last question, do the amount of facets have anything to do with the sparkle? While looking at reports I noticed some diamonds have a lot more chevrons, how does this play into the diamond?
Example:

I'm looking at diamonds directly from Ritani. They don't set other diamonds in the rings so that pretty much limits me to their inventory. For reference this is the ring I'm looking to set the diamond in:
