I had the hardest time figuring out which lab diamond to get, too. Of those two, I would go with the G becuase of the excellent cut/symmetry/polish. But head on over to and use their HCA tool to gauge optics and light return. Ideally, you want a number between 1-2, but that’s not easy to find. My diamond is a 2.3 and sparkles like crazy.

You get three free tries before you have to pay. Good luck!!

katek90 :   I agree with PP – enter the specs on Pricescope’s HCA tool. I also prefer GCAL grading reports as they are more accurate and informative.
