Those that bought lab growns in IGI cert gonna have big regrets man. The gradings are way off. Best is to just stick with GIA or AGS.
Ooo the guy we consulted with at JP also mentioned the same! IGI gradings are very off compared to AGS/GIA. I think he mentioned their lab-grown diamonds are certified by AGS but best to check again directly with JP during consultation.
However, since their lab-grown diamonds do not enjoy any trade-in/upgrade policy, I guess it's safe to say lab-grown diamonds do not retain any value, unlike natural diamonds - regardless of how much JP evolves the process to minimize the stria issues.
