Tumbling rough ruby

Hello Everyone Own bead and cab grade ruby rough with skin. Though
dealing in gems, have no experience whatsoever of processing the
rough. Any suggestion as to if tumbling is a good idea (my take is -
with skin gone it will facilitate in separating cab from bead)? If
yes, then what would be good tumbler the brand (not for more than 5
to 10 pounds at a time) and the process Any experience that can be
shared Thanks for the time Aneil
