A couple of questions about my engagement ring...

Hi Everyone,

Sorry that this is so long!

I posted here when I first got engaged, back at the beginning of December. I was concerned about the symmetry of the prongs on my setting. Since then, I have had it worked on a few different times at the same jeweler. I'm still really not sure that I'm happy with the symmetry of the prongs. I understand that some minor asymmetry is expected, since diamonds aren't 100% symmetrical, and also because princess cuts apparently show asymmetry more than other diamonds. I have attached a few pictures - would you say that the difference in the prongs is acceptable, or that they should be more symmetrical?

Also, a little background information on the diamond: my fiance and I picked it out together at a local, reputable jeweler. They pride themselves on great cuts, and they have great reviews. It is a GIA-graded 1.53 carat princess cut, F color, SI1 clarity (totally eye-clean - the grade-making inclusion is a crystal, and I believe that it's white, and not dark-colored, followed by clouds and an indented natural), with excellent polish and excellent symmetry. I don't have the report with me right now, but I remember that the spread is 6.37 mm x 6.34 mm, and the table is 71%, with a 71.6% depth.

I know that the numbers probably can't tell us much, but I am just curious about the expected amount of sparkle that a well-cut diamond projects in various lighting conditions. It was difficult to tell the difference between the different diamonds at the different jewelry stores (they all sparkled like crazy in that lighting), but it definitely sparkles a ton at the mall, on elevators, and in some of my house lighting (I don't even really have to move for it to shoot off tons of tons of sparkles). Under the lighting at work, though (I work in a hospital, with florescent lighting), and when I'm outside but then sun is behind the clouds, it sparkles much less. I guess my question for those of you with well-cut diamonds is, do they still sparkle a ton in these lighting situations? I truly do believe that my diamond is beautiful, but I want to make sure that it is well-cut and that it gives off the expected amount of sparkle.

What are everyone's thoughts? The jewelry store does offer an upgrade option, with no minimum purchase amount. If it came down to it, we could pick another diamond. They only have GIA and EGL-certified stones, but they have a very large selection. I could also bring it to another jeweler to fix the prongs, if there is a way that they could be fixed further. I doubt that the original jewelry store would know the difference, since the changes would only be minor.

Thoughts? Thank you so much for your help!
