I would be wary of other grading labs. According to some other research studies, non GIA & AGS certs actually may cost more. They are not cheaper.
1) Non-GIA & AGS certs tend to be graded of a higher grade. But when re-graded by GIA / AGS, very often, they have lower grades assigned.
2) Although, it would be cheaper when compared to diamonds of the same grade as GIA/AGS, if we use the actual GIA/AGS grade, one may actually be paying more for their stones.
My word of advice. Non GIA/AGS certs may not mean a better deal.
I have actually seen an IGI Ideal H&A before. It was a 0.75ct E VS2 3EX Ideal H&A as stated in the IGI Ideal H&A report. I was given the opportunity to compare the color with the other 2 GIA stones ( F color & E color) side by side for color comparison. All these 3 stones are placed with pavilion facing up on a white paper under a gem light. I can actually see that the GIA F color is more yellowish than the GIA E & IGI E color. But I can't see any difference between the GIA E & IGI E.
As for the clarity i compared with a GIA VS2 & GIA SI1 under a loupe and the GIA SI1 seems to be the most included. Both VS2 looks clean to me.
Lastly when i inspected the IGI Ideal H&A with Aset scope i found that the IGI Aset image is better (even Classis girdle, Perfect Optical Symmetry and no light leakage) than the other 2 GIA 3EX.
In this case, what do u think of these IGI Ideal H&A if the price is the same as GIA 0.75 E VS2 3EX? Do you think it is worth to consider in this situation?
Anyway, I didn't choose either as both exceeded my budget.
