Well for one, we don't know if the picture is to scale, and we've really seen a few gems with diamond cuts ( the Heaven Beetle, unknown Fluorite component). It would be too much of a coincidence for this gem to have to have a diamond shaped gem AND have it be on her navel for her not to be Pink Diamond.
