I just did a quick search and found these:

7mm princess cut

7.5mm princess (not prime)

1.5 ct princess cut

2ct princess cut - free try on with Amazon prime wardrobe

2ct with a halo

Amazon I'm sure hates me, but I ordered probably close to 20 rings to try on when I was doing my ring search, and ended up returning them all because the returns were free. You just have to be honest when you return them (didn't fit, or didn't like it, or changed mind)... I know they get irritated when people claim a product has a defect when it doesn't.
