Hi everyone, I've been a long time lurker and have learnt so much on this forum. I've just been deciding on a diamond for a birthday present, and these two fit my budget and was wondering which one would be better and why. The second stone only costs $20 more but I was hoping to not go lower than an I color, though the VVS2 in the second stone makes it seem better value. The first stone has a HCA score of 1.6 whilst the second one has a score of 2.0. Any advice is appreciated, Thanks in advance!
