We use the products that we sell and almost always have at least one rock tumbler running. We do this to continue learning about rocks, the machines used to tumble them and the methods of rock polishing. We also do this to know which products we should be selling and which products we should not.

Many websites sell rock tumblers and then you are on your own. If you have a question about rocks or rock tumbling it is impossible to get in touch with them. Or, if you can get in touch with them, they don't know anything about rock tumblers.

If you purchase a rock tumbler from us and need help, we are here to answer your questions. We also share our knowledge with the public by publishing what we believe is the largest library on the web of articles, videos and blog posts about tumbled stones and rock tumbling.

The tumblers we are running

There are limits to our abilities and knowledge. We will do our best to answer your questions about tumbling rocks, but if you want information about tumbling other things, or using a rock tumbler for another purpose we will probably tell you that we don't know anything about it. is located in Lemont Furnace, Pennsylvania. We sell rock tumblers, rock tumbling supplies and tumbled stones to customers within the United States. All of our sales are online. We do not have a walk-in store.

tons of stone

We really like tumbled stones. At any given time we have a few tons of stones from all over the world in our warehouse that are available for immediate shipment to fill your order. All of the stones that we have available for sale can be found on this page of our website.

We regret that we are unable to custom-select stones of special sizes, shapes or colors. That type of work is extremely time-consuming and as much as we like examining tumbled stones our small staff is unable to provide that type of service. If you need stones of special sizes, shapes or colors, the best way to obtain them is to visit a rock shop, crystal store or museum shop where visitors are able to hand-select their stones. All of our sales are online and by mail. We do not have a walk-in store. Sorry.

Rock Identification

It is very difficult to identify rocks from photographs because the observer can not view them from various angles, view them under different types of light, examine them with a lens, determine their hardness, clearly see their texture and do other tests.

The best people for identifying rocks are those who live near where the rocks were collected and are familiar with the local rock units and geology. Local rock shops, rock clubs, university geology professors and geological surveys are sometimes willing to do this, but it is best to ask before travelling to them to avoid disappointment.

We do not offer a rock identification service at our office, by email or through the mails.
