Hi Joseph,
Thanks for creating this great resource. Would you mind giving your take on these two lab diamonds? I couldn’t attached a picture for the bottom one. The bottom one is from 1215diamonds.com and seems like too good of a deal.

Hi David,
There’s not enough information here – the grading reports are not enough. Lab diamonds in the H/I/J range more often than not tend to be brown (CVD diamonds start brown and are HPHT treated to improve their color), so you’d need to see a video to evaluate color. Lab diamonds also have different growth patterns that often show themselves as layered striations that you’d want to avoid (see: https://www.gia.edu/gems-gemology/fall-2016-observations-cvd-grown-synthetic-diamonds-review). Again, you can only see that in videos.
I will say that the first diamond has table > depth and typically you’d want it the other way around, as described in my princess diamond guide. But I do tend to prefer the 3 chevron pavilion facet pattern of diamond 1 over the 4 chevron pavilion facet pattern of diamond 2. Diamond 3’s link is not a grading report.
