I think in this particular case, the woman may be demanding, insensitive, and shallow.
But, no, I would not automatically say that a woman cannot say anything if the ring is just not 'right'. Choosing a ring is perhaps the first thing where a couple may need to learn to compromise!!! If the man wants to surprise his fiance, that is great, but her wishes and tastes should be respected as well.
I actually said someting about my ring after my DH proposed!!!
We were young and penniless. So, believe me, it had NOTHING to do with wanting a bigger or more perfect ring. However, to put it very simply, my DH was one of those young guys who was not the most knowledgable about jewelry. The biggest thing is that the ring was just not quite right for me. With my hands, I really needed and wanted something different. (a Marquis to look right on my hands and fingers....)
Well, just like the couple in the OP, we went back to the jewelry store (maybe to see about sizing????) they happened to be having a big sale. All solitaires were marked down, and there was this beautiful little Marquis that was a better diamond, and actually the same price or less than what my DH had picked out with the sale going on.
He had no problem making the switch!!!
