Two vendors, two completely different cut grading

[Versace]

Hi everyone

I'm interested in following stone, but noticed that the same diamond has been given an EXCELLENT cut classification by one vendor and only GOOD by another. How can there be such a big discrepancy between the two ratings?

Thanks.

Ignore the gradings posted by different vendors. Different companies use different algorithms to filter their inventory. Effectively, they are still the same stone and they are "perceived" differently. The information as a result, can be misleading.

I would check the GIA certificate itself for any cut info.

GIA currently doesn't offer a cut grade for fancy shapes.

I think this is common problem filtering the Fancy shape stones, every online store has different formulas to grade
cut and same stone can differ in Cut grade, this leads to confusion, GIA does not grade the Cut of Fancy stones.
Maybe you could contact the Customer Service of both the companies and ask how they grade the cut as Excellent,
what parameters they look into while grading, it may help.

the GIA report says excellent excellent but polish and symmetry not cut sorry
