    I think that this depends on which onyx is being discussed. The term
    onyx is applied to  banded calcite and also to Brazilian agate which
    has been dyed black. The original onyx is a black, brown and white
    banded agate. It is the banded calcite which is often polished by
    acid-dipping and which is probably too soft to fare well when
    tumbled with steel shot.
