Are you rejecting stones with a score >2 or <2? The HCA score is a rejection tool not a selection tool. A stone >2 is recommended to be rejected but if you can see the diamond in person and it performs very well the HCA doesn't matter. A 0.6 vs a 1.5 wouldn't matter because they are both below 2 and it isn't a selection tool. I assume you know this but just in case. That diamond looks fantastic, if you are like me you are probably obsessing over every little detail to find the best stone possible. At the end of the day, I'm sure your gf would be ecstatic with all of the choices you have. Good luck!
Yeah, I'm using it as a rejection tool. This one was a 1.0. The other one I have coming is also 1.0. And you're right. We're obsessing about every little detail at this point, and I'm sure there are others also thinking it's not enough (aka super ideal unicorn cut) haha. Thanks for the support.
