How to cut and polish opal

How to cut and polish opal

Cutting opal requires a high level of skill and a lot of patience. By studying the rock and opal formation, one can start to work out how the opal runs through your material. We begin by slicing with the diamond saw and removing any unwanted material. This will also help to reveal where the colourful opal veins or layers are running through your rock.







Once the opal layers or veins are located we then carefully and slowly grind away any rock or colourless opal to reveal the coloured opal beneath. This is done with grinding wheels first and then sanding disks to carefully expose the colour bar.


We then shape the stone to bring out the best of the opal and it's features.


Many hours of work go into the cutting, grinding, sanding and polishing of each and every opal. There is no quick way and only patience can bring out the best of the opal's colours and features.
