Since the name Ring is already taken by an ubiquitous mathematical structure, and thus already in hackage for example as Algebra.Ring in the numeric-prelude , I suggest to call the data structure Necklace instead.

Is Necklace a known name for this data structure? If not Ring, I was thinking Circular might be an appropriate name.

I'm not sure if there's a canonical name, except perhaps "circular queue". Necklace is cute, though Circular or CircleQueue might be better. I'd also advise strongly against using Ring in order to avoid confusing nomenclature. (Loop should be avoided for similar reasons.) When reading "Ring" first time in the e-mail subject, I also thought it would be about the algebraic structure with that name.

CircularList seems fine to me. Necklace is nice but might be missed when someone searches for that data structure on Hackage.
