As you’re practicing your opal-cutting skills, feel free to check in with this post to make sure you have all the steps down pat! While it may take a bit of elbow grease to master the art of opal polishing, nothing is more rewarding than knowing you can polish an opal right in the comfort of your home.
Choose the right tools for cutting and polishing an opal
Those just starting to learn how to polish an opal at home will be surprised to know that you’ll only need a few pieces of equipment.
On that note, learning about sandpaper grit and knife hones can be intimidating for those who have never tried hand-cutting opal. Here are a few rules to keep in mind:
- Find knife hones that can be wet with water. Some knife hones rely on oil to get the surface wet, but the problem is that opals can be quite porous. Corundum knife hones last quite long, making it perfect for beginners who’ll need a bit of trial and error!
- Make sure you’re working with different sandpaper grits. If you stick to just one type of sandpaper grit for your project, you’ll most likely end up ruining the opal entirely.
- Work with the right type of leather. Like sandpaper, leather can be hard, soft, or somewhere in between. It’s best to ask for advice from someone cutting opals for a long time when deciding what kind of leather to use.
- Keep yourself clean. Last but not least, you’ll want to ensure you’re keeping your workstation clean while working on cutting and polishing that opal! Our top tip? Keep an apron on so that your clothes don’t get dirty from the dust.
Manage your expectations when cutting and polishing opal
As we mentioned in the video, the process of cutting and polishing an opal takes a lot of time. If you’re starting to figure out how to polish an opal, you should expect the entire process to last up to five hours on your first try!
As with anything, you’ll eventually speed up as your skills improve. Since you’re working with such a delicate piece, you’ll want to spend time with it. Plus, going slower means you can gradually see the colors of the opal change before your eyes, just like magic!
The best advice for how to polish an opal is to start with lower-grade stones. Beginners need to get comfortable with hand-cutting an opal, so working with a high-grade stone right off the bat can make the process more stressful than enjoyable.
