Help with princess cut halo measurements!!!!!!!

[phillip9698]

Im having a ring made for my princess cut diamond which measures 5mm square. The CAD image the jeweler sent me has the total halo size at 9.94mm. Im wrecking my brain trying to picture how large that would look on my girlfriends size 6.5 finger.

Can any of you with halo rings let me know the size of your halo and how it looks on your hand? I dont want the halo to just engulf her hand so a visual reference would help.

Thanks.


Here is the CAD .
