I noticed some stones on the (lab-created) price tracker are denoted as “Ideal Proportions” but when I look at the lab report they fall outside both GIA EX/AGS 0.

An example is James Allen SKU:7203029. The IGI report says table 58%, crown 34.9, pavillion 40.2. When I plug that into the cut estimator it falls in GIA VG/AGS VG.

In fact, not a single IGI report I’ve requested for lab grown diamonds fall in either GIA EX/AGS 0. Am I doing something wrong?!

Thank you!
