The only ring I've ever noticed being different is the engraved one that has 80 and a bunch of other stuff engraved on it. I have no idea what magazine I saw that picture on or even when in the last 30 years. I just remember I thought it was so personal and cool. Most of the time when people engrave rings they do it on the inside and I'm always thinking, what's the point of that? It'll wear out and you don't get to see it. Other than maybe a change in metals, I generally don't notice the difference in wedding bands otherwise even on my friends! I am also a bridesmaid in an upcoming wedding and I had to be told the bride changed her mind and got a different dress than the one we picked out together. I'm not the most observant.
