Charlevoix stone is a type of igneous rock that is found in the Charlevoix region of Quebec, Canada. It is a rare and unique rock that is prized for its beautiful and varied colors, patterns, and textures. The rock is believed to have formed over 400 million years ago, during the Silurian period, as a result of volcanic activity.
In terms of physical properties, charlevoix stone is relatively dense and hard, making it suitable for lapidary work. However, its hardness can vary depending on the mineral content, so it’s important to consider the specific type of charlevoix stone you are working with. Additionally, some charlevoix stones may contain fractures or inclusions that can affect their appearance or durability.
There are currently no restrictions on the collection or use of charlevoix stone, but it is recommended to obtain permission from the land owner before removing any rocks from their property. Charlevoix stone can be found in various locations throughout the Charlevoix region, including riverbeds, cliffs, and outcrops.

Polishing charlevoix stones using NATIONAL GEOGRAPHIC Rock Tumbler
Polishing charlevoix stone with a rock tumbler is a relatively straightforward process that can produce beautiful, polished stones. Here is a step-by-step guide for a rock tumbler to help you get started:
- Gather materials
You will need a rock tumbler, abrasive grits (such as coarse, medium, and fine), water, and charlevoix stones.
- Clean stones
Before you begin, it is important to clean your charlevoix stones to remove any dirt, debris, or impurities that could affect the final result. Rinse the stones in water and let them dry completely.
- Load tumbler
Fill the rock tumbler barrel with your charlevoix stones, making sure to leave enough room for them to move freely.
- Add abrasive grit
Add the coarse abrasive grit to the tumbler barrel, following the manufacturer's recommendations for the amount to use. Add just enough water to create a slurry that covers the stones.
- Run tumbler
Turn on the tumbler and let it run for 7-10 days, depending on the size of your stones and the desired result. The tumbler should run continuously during this time.
- Change grit
After the first stage of tumbling, remove the stones from the tumbler and rinse them in water. Then, refill the tumbler barrel with the stones and add the medium abrasive grit. Repeat the process for another 7-10 days.
- Repeat with fine grit
After the second stage of tumbling, repeat the process with fine abrasive grit. This will produce a smooth, polished finish on your charlevoix stones.
- Final rinse
Once the final stage of tumbling is complete, remove the stones from the tumbler and rinse them in water. Let them dry completely before using or displaying them.
With these steps, you should be able to polish charlevoix stones using a rock tumbler to create beautiful, polished decorative objects. Just remember to be patient and allow enough time for the stones to be polished to your desired result.
