Hello all you people out there in jewelry land! Does anyone know
how to polish red branch coral? It is in it’s natural state.Thank
you and wish I was going to Tucson! S.Bradley
I have always used triploi & rouge for polishing these stones.
Works fine for me. I understand that malachite is poisonous for
people that are polishing large quantities. I also clean these
stones in the ultrasonic cleaner and steam. If left in the
cleaner too long, they will come out dull. Coral is hard to clean
of rouge. The remedy here has been to rub the coral down with an
application of mineral oil after the ultrasonic has dulled the
finish. Took me about 25 years to find this solution.
