One of the more popular beach accessories where I live is a mood toe
ring. These are similar to the 1970s mood rings, except they are smooth
bands of color instead of the classic rounded domes. Also, I've seen
reddish tones in the newer rings that weren't available in the first
rings. The original mood rings had a nasty habit of self-destructing if
you got them wet, which I can verify isn't a problem with the modern
Mood rings supposedly change color to show your emotions.
