Can You Put Quartz in a Rock Tumbler?

Rock tumbling is an exciting hobby for geology enthusiasts and hobbyists alike. It is the process of turning rough stones into polished and smooth ones through the use of a tumbler. A rock tumbler uses a barrel, grit, and water to grind, polish, and shape rocks.

One of the most common questions that come up regarding rock tumbling is whether or not you can put quartz in a rock tumbler.

In this article, we will discuss everything you need to know about tumbling quartz.

What is Quartz?

Quartz is a mineral that is found in many types of rocks, including igneous, sedimentary, and metamorphic rocks. It is one of the most abundant minerals on Earth and is made up of silicon and oxygen atoms. Quartz has a wide range of colors and can be translucent, opaque, or transparent.

Can Quartz Be Tumbled?

The short answer is yes, quartz can be tumbled. However, there are a few things you need to keep in mind before you start tumbling your quartz. Quartz is a hard mineral with a Mohs hardness of 7, which means it is quite tough and can withstand tumbling.

However, it is important to note that the tumbler’s barrel should be at least half-filled with quartz to ensure proper tumbling.

How to Tumble Quartz in Rock Tumbler

Choosing the Right Grit

To tumble quartz, you will need to use the right grit. The grit is the material used to grind and polish the rocks in the tumbler. The grit comes in different sizes, and each size has its specific use. When it comes to quartz, you will need to use a coarse grit, a medium grit, and a fine grit.

Coarse grit will help to remove any rough edges and shape the quartz. The medium grit will further smooth out the rough edges, while the fine grit will give the quartz its final polish.


Water is an essential component of rock tumbling. It helps to lubricate the rocks in the tumbler, preventing them from getting damaged.

When tumbling quartz, it is important to ensure that the tumbler has enough water. If the tumbler does not have enough water, the quartz may become overheated and crack or fracture.

Tips for Tumbling Quartz

  • Start with a Clean Tumbler: Before you start tumbling your quartz, make sure the tumbler is clean. Any dirt or debris left in the tumbler can scratch and damage the quartz.
  • Use the Right Amount of Grit: Make sure you use the right amount of grit. Too little grit will not be effective in tumbling the quartz, while too much grit can damage it.
  • Keep the Tumbler Half-Full: The tumbler should be at least half-full with quartz to ensure proper tumbling.
  • Check the Water Levels: Check the water levels regularly and ensure that the tumbler has enough water to prevent the quartz from overheating.
  • Be Patient: Tumbling quartz takes time, and you need to be patient. It can take several weeks to get the desired polish on your quartz.


In conclusion, quartz can be tumbled, but you need to ensure that you use the right grit and the right amount of water. Tumbling quartz can take some time, but the end result is well worth the effort.

With the tips provided in this article, you should be able to successfully tumble your quartz and turn it into a beautiful polished rock.
