I didn't have pictures or video for the stones.
GIA REPORT NUMBER: 6415219897
I input the data and get the hca score 3.1 as below,
Diamond screener cut estimator shows that it is slightly out of AGS Ideal based on proportions.
It is just a guidance tool though. One good thing is that diamond screener cut estimator will show you how diamonds with similar proportions (table, crown angle, pavilion angle) look like at the bottom. From the looks of it, they are acceptable, but can be better. You try change your pavilion angle to 40.8 and see the sample diamonds. They look better.
Nonetheless, since you mentioned that you do not have any video or picture, then I assume it is a physical stone in a physical store. You can try to request to view the hearts and arrows using the scope, see if the arrows are at least straight and tidy.
You can also compare the diamond against any signature diamonds (if any) in the store. Not all shops have a signature range though.
Lastly, do compare prices and see if the price is okay.
