Supply Description
Polishing grits These are abrasive compounds used to smoothen and polish rocks. They come in different grit sizes, ranging from coarse to fine. The grit size you select depends on the level of polish you want to achieve and the hardness of the rocks.
Tumbling media This is a filler material that is added to the rock polisher to provide cushioning and prevent the rocks from sticking together during the tumbling process. You can use a variety of media, including plastic pellets, ceramic cylinders, or corn cob.
Water Water is needed to lubricate the rocks and grit, which helps to prevent them from breaking down during the tumbling process.
Rock separator A rock separator is useful for separating the rocks from the polishing media after the tumbling process is complete.
Accessories Other accessories, such as a grit scoop, can be useful for transferring the grit and media into the rock tumbler. A plastic bowl or bucket can also be used to clean the rocks after the tumbling process.

It is important to use high-quality rock polishing supplies to achieve the best results. Cheap grits and media can break down quickly and result in an uneven or incomplete polish.

When purchasing rock polishing supplies, consider the quality and reputation of the supplier. The best rock polishing supplies are those that are designed specifically for rock tumbling and come from reputable suppliers.

Rock Polishing Tips and Techniques

Rock polishing is an art that requires patience and attention to detail. Here are some valuable tips to help you achieve stunning results:

  1. Selecting the right rocks: Before you start polishing, make sure you choose the right type of rock. Harder rocks such as quartz and agate tend to polish well, while softer rocks like calcite may crumble or fracture during the process.
  2. Cleaning the rocks: Be sure to clean your rocks thoroughly before placing them in the tumbler. Any dirt or debris can scratch the surface of the rock, ruining the polish.
  3. Choosing the appropriate grits: Start with a coarse grit, around 60-90 mesh, and gradually work your way up to finer grits. The final polish requires a very fine grit, usually around 2000 mesh.
  4. Adding tumbling media: Tumbling media are small pieces that help to cushion the rocks during the tumbling process. Plastic pellets, ceramic cylinders, and steel shot are commonly used.
  5. Timing the tumbling process: The length of the tumbling process depends on the type of rock and the desired outcome. It can take anywhere from a few days to several weeks to achieve a polished finish.
  6. Additives: Some people add polish to the final stage of the process, but it’s not always necessary. Cornstarch or baby powder can be added to the final polish to help prevent the rocks from sticking together.
  7. Checking for progress: It’s essential to monitor the progress of your rocks regularly and clean them after each stage to avoid contamination.
  8. Troubleshooting common issues: If your rocks are not achieving the desired polish, try adjusting the amount of grit, tumbling time, or changing the type of tumbler media.

By following these tips and techniques, you can achieve a stunning polished finish on your rocks. Remember to experiment and have fun with the process, and you’ll be amazed at the beautiful results you can achieve.

Rock Polishing Techniques for Beginners

If you’re new to rock polishing, don’t worry! With the right tools and techniques, you’ll be creating stunning gems and stones in no time. Here are some tips to get you started:

Selecting the Right Rocks

Not all rocks are suitable for polishing. Look for rocks that are hard and non-porous, such as agate, jasper, or quartz. Avoid soft rocks like limestone or sandstone, as they will crumble during the tumbling process. It’s also important to clean the rocks thoroughly before polishing to remove any dirt or debris.

Setting up the Machine

If you have a rotary tumbler, fill the barrel about two-thirds full with the rocks, water, and abrasive grit. Make sure to follow the manufacturer’s instructions for the right amount of grit to use. Seal the barrel and turn on the machine. A vibratory tumbler is slightly different. You’ll need to place the rocks, water, and abrasive grit in a bowl or bucket and then place it on top of the tumbler base. Turn on the machine and let it run for the recommended time.

Choosing the Appropriate Grits

The tumbling process involves progressively smoothing and polishing the rocks using different grits. Start with a coarse grit and gradually move to finer grits. Most beginners find that three to four stages of grit are enough for a polished finish. Refer to the manufacturer’s instructions for recommended grits and times for each stage.

Achieving Polished Results

After the final polishing stage, remove the rocks from the barrel and clean them with soap and water. Dry them thoroughly and inspect each rock’s surface to ensure a smooth and polished finish. You can enhance the polish by using a rock tumbler burnishing powder or fine aluminum oxide powder to give them extra shine.

Rotary Tumbler Vibratory Tumbler
Advantages Cheaper and quieter Shorter tumbling time and smoother finish
Disadvantages Takes longer and may require more grit Louder and more expensive

Remember, practice makes perfect! Don’t be discouraged if your first few batches don’t turn out as expected. Experiment with different types of rocks, grits, and tumbling times to find the right combination for your desired results.

Maintenance and Care for Rock Polishers

Proper maintenance and care are essential for ensuring the optimal performance and longevity of your rock polishing machine, whether it’s a professional rock polisher or a beginner-friendly model. Follow these practical tips to keep your equipment in top working condition:


After each use, it’s essential to clean your rock polisher thoroughly. First, unplug the machine and disassemble it. Remove the barrel and rinse it with warm water to remove any grit or debris. Use a soft brush or cloth to clean the other parts of the machine, taking care not to damage any delicate components. Avoid using abrasive cleaners, as they can scratch the surface of the machine and affect its performance. Rinse all parts well and let them dry completely before reassembling the machine.


Regular lubrication is vital for keeping your rock polishing machine running smoothly. Consult your machine’s manual for specific instructions on how to lubricate it properly. In general, you can use a light machine oil to lubricate the motor’s bearings. Apply a few drops of oil to the motor’s oiling points and run the machine for a few minutes to spread the oil evenly.

Belt and Motor Maintenance

Check the belt and motor regularly for signs of wear and tear. Replace any damaged belts or pulleys immediately to prevent further damage to the machine. Lubricate the motor’s bearings regularly, as mentioned earlier, to keep the motor running smoothly.


If you encounter any issues with your rock polishing machine, consult the troubleshooting section in your manual. If the problem persists, don’t hesitate to contact the manufacturer’s customer support team for further assistance.

With proper maintenance and care, your rock polishing machine can provide years of reliable service and stunning results.
