natural stone bangles, bracelets or large stone ring handles or curtain tie-backs

Two natural stone bangle bracelets, or curtain tie-backs, or handles, or ??? Size is 2 1/2" diameter across the opening, 3 1/4" across the whole thing.

I don't know if these are jade or soapstone or something else, though we think they're probably Asian in origin? Both look good, without chips or cracks.
