Privacy Notice

We use the products that we sell. We know how they work and how to use them well. We almost always have at least one or two or three or four rock tumblers running. We do this to continue learning about rocks and the machines used to produce tumbled stones. We also do this to know which products we can recommend and sell with confidence - and which products do not merit space on our website. We don't sell stuff that doesn't work! :-)

Many websites sell rock tumblers and then you are on your own. They don't have detailed product descriptions or articles that tell you how to decide what to purchase and how to use it. You can't get in touch with them after the sale. If you have a questions they don't have detailed answers on their website. And, if they have contact information they don't know anything about the products that they sell or they don't answer your calls or messages.

We aren't like that!

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. Everyone on our staff knows a lot about rocks, minerals, gems, tumbled stones and rock tumbling. We are a member of the International Gem Society and our staff members have created the articles on rocks, minerals and gemstones that are published in, another website owned by our parent company.

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 using a rock tumbler for some other purpose, we will immediately tell you that we are unable to help. Some people think that rock tumblers are miracle cleaning and polishing machines, but that is a myth most of the time. So, we will not give you guesses that will likely waste your time. 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.
