Small-Sized Rough

Easy-to-tumble rocks for beginners and small rock tumblers.

This photo shows a 2-pound package of our rough Ohio Flint. Notice the range of sizes. Having both larger and smaller pieces in the tumbler is ideal to get the most effective tumbling action, as discussed in our article and in the book Modern Rock Tumbling by Steve Hart. Click for a larger photo.

EASY:

The rock tumbling roughs sold on this page are easy-to-tumble materials that are perfect for small tumblers. They are sold in two-pound packages which contain small pieces that range from approximately 3/8" (9 mm) to 1 1/2" (38 mm) in size (see photo above - it is an example of the range of sizes you may receive).

These small-sized roughs are intended for use in small rock tumblers with a 2-pound or 3-pound capacity barrel, such as the Thumler's MP-1, Thumler's A-R1, and Lortone 3A. They are "ready-to-tumble" and have a Mohs hardness of about 7. They work well without adding media, using the instructions shown on the page where the rough is sold.

Please Note: If you are an experienced tumbler who wants to create larger tumbled stones, these roughs are not for you. Check out our selection of chunky roughs instead.
