Yeah I didn't want to pick mine either. He asked what kind of styles I like and he had researched cuts and stuff which I still really don't know anything about so he would be like "cushion cut? Princess cut? This? That? InchHigh, pay attention. Look at these on my iPad" and I was like "I don't like yellow gold. Other than that, surprise me!" He did a great job. I don't know that I would have picked this one, but I love it and I think it's so beautiful and I love how he became a little ring expert. He was all "look, let me explain the clarity because it might not be as big as you expected, but....the clarity..." He was SO cute!!
but to answer the question, I was more interested in what he would pick and why and when. And also, I'm not very into detail, so I honestly didn't feel like picking a ring
