This gives people the unique experience of polishing genuine Australian opal. There is nowhere else where you can polish opals and it is very likely that the opal you leave with will be worth more than the money you spent on this workshop. In fact, potentially you could polish an opal that is worth hundreds of dollars as it is impossible to see what an opal will look like before it's been polished, so it is truly the luck of the draw. But we give you the information to help you make an informed choice of the parcel of opals you choose. Opal is becoming increasingly valuable with all opal rough being snapped up and it's not going to get better in future as some opal fields are being closed down. This truly is the opportunity of a lifetime.
