Congratulations, Honeywolf!
I second what RUDisney said about pearls. Although they are beautiful, they are a softer stone and don't do as well if you're planning to wear it every day. Although I'm like lil mermaid and I love diamonds, I decided to forgo getting an engagement ring when I got engaged. Since I had been married before I wanted my wedding band to be the important ring and told my DH I'd rather him give me a big diamond ring on our 10th anniversary when it would really mean so much more. (Which he did). But, for my wedding ring, we had designed a small gold wedding band with one small emerald in the middle, surrounded by two small diamonds. After 13 years of marriage, I am stopped all the time be people admiring my "small" ring. It's very special and unique. So, think what would be special and unique for you and Roger. And, of course, let us know!
