Oh thank you for thinking of me, @Kim N
I’m no good with spotting possible differences on CAD unless I have OP’s specific inspo pictures to compare to.
I think(?) Tiffany changes their designs over the years, and the difference between center stone size design nuance is real.
OP if I were you
I’d search up known Tiffany inspired whether it be from this same vendor, Vatche’s version or elsewhere, and compare those nuances to what you envision in your mind for your own ring. Real pictures - not computer renderings.
And that in itself might really help you.
If you search throughout PS - you’ll possibly even find threads with CADs along with the finished product.
Thank you! Appreciate your advice.
