by septsparkle » Aug 21, 2010 Okay, so now that I've had both the princess cut and the round stones in my possession for a few days I've compared them side by side quite a bit and I honesty do not see a difference in the size. The measurements for the princess stone are 1.366ct and 6.40 x 6.10 and the RB 1.39ct and is 7.18 x7.22. That's almost an entire mm larger then one side of the princess cut stone and I just don't see it! I really think it is a matter of the area because somehow my eyes are able to balance out the corners of the princess with the roundness of the RB and they truly do look the same to me. Here are a few photos I took trying to compare the size....what do you guys think? Do you really think the RB faces up larger then the princess?
