Grooved for o-ring snugness.
Approximately 3/8" wearable with o-ring on.

Love these! One of my favorites. Great for everyday wear because they are super light.

Maybe these are better in other colors or larger gauges but the 2g clear look like cheap cloudy plastic, you can hardly see the glitter at all.

The pink is a little pale. :\ I don't wear these much because they don't sparkle much.
