I ordered this ring in a size 9 so I could wear it on my middle fingers or my thumbs. I was afraid the symbol may be too small, but it wasn't; it was perfect!! If you order it in a small size though, it may be too big. Something to consider...as it could wrap around your finger a little instead of being able to see the entire infinity. I'm super happy with my purchase and have been wearing it non-stop since it arrived!
I don't understand why someone said this ring is so small that it will 'disappear into your finger". It's not small at all. View the photo of the ring on the girl's finger and see it's size. It's actually the perfect size. I bought the silver and it's a nice silver - next to my platinum ring, cannot tell it's silver - looks platinum!
