Hand polishing an opal: Can it really be done?

Is it easy to do and how long does it take? Justin shows you how to hand polish an opal..

Recently I bought to you Steiner Florian’s story about hand polishing opal.

You asked the questions and Steiner was on hand to reply. How long does it actually take and can it really be that easy to do?

Watch this video as I try the  “The Steiner Technique” on hand-polishing an opal.

In order to complete this  ‘little exercise’  you will need.

  • Knife sharpening block
  • Sandpaper wet & dry 400 Grit to 1200 Grit
  • Towel
  • Dop Stick
  • Jewellers Wax
  • Strip of leather
  • Cerium Oxide
  • Spray bottle with water

Watch this video as Justin gives hand-polishing a go. He shows you at the start of the video what he is going to polish. In an easy to view format he easily explains what to do…”his handy hint is ‘don’t push too hard on the stone as you can easily chip the stone”and after 2.5 hours he shows you the end result… a lovely polished opal!

Yes it really is that easy

Yes it does take a bit of time

Take a look at the video..give it a go and let us know how you go..

  1. I’d love to give it a go, as an apprentice jeweller im a dab hand with the wet n dry, but no idea it could look/ be that simple a process. Now to buy an inexpensive rough in case I trash it, lol.

  2. I have done a LOT of hand polishing of opals over the years-it certainly makes you appreciate your cutting equipment but yes it can be done with lots of patience 🙂

  3. justin i followed your vid on you tube on hand polishing i noticed you op out of wearing goggles or protective glasses let me tell you if cerium oxide gets in your eyes it hurts believe me and i had a sore eye for for over a week so i think people need to be put in the picture about that william glitterboy2000

    • Wow that is not good. I have not had cerium in my eyes and have been cutting opals for the last 25 years. I hope it never happens.

      • I live in the Mojave Desert and I am not sure what I have had in my eyes. When it gets uncomfortably gritty (during major windstorms) I set the water to an eye-comfortable temperature and run copius amounts over my eye(s). This is kind of standard first aid for many foreign substances in the eyes. If you love your eyesight, a trip to the opthamologist is probably in order. If the water makes all of the discomfort go away, I usually wait a day before trekking to the urgent care.

    • You don’t need to buy any just go to the hardware store and buy some Dal wood. Rounded wood you can cut into small pieces for dop sticks
