Unfortunately GIA reports tell us very little about fancy cuts. We'll need to see up close pictures, asets and videos would be helpful.
Can you request thsee things and post what you are able to get.
You might also work with a vendor like james allen that can provide the info that we look need/look for.
You can't go by numbers. You have to have magnified images of the stones at the very least. ASET images are useful in evaluating light return as ovals aren't usually among the more brilliant stones. The only thing the numbers might tell you is if a stone is excessively deep or table too huge or something like that. But you cannot choose any fancy shape diamond by a grading report.
I've looked at the stones under the magnifying loop.
James Allen had only one oval in my price range yesterday and as I'm in Dubai I wan to take advantage of that but sadly they don't have many ovals. The place is full of rounds!
The only thing the loupe is useful for is to look for inclusions. Other than that, it is useless to shop by the numbers and anyone who suggests such has no clue what they are doing. Unless you provide clear magnified pictures of the ovals in question, I am afraid that there's nothing anyone here can tell you about the ovals.
