Who Are You Doing Business With?

We have been running rock tumblers for almost 50 years. We use the products that we sell. We know how they work and how to use them. We almost always have multiple rock tumblers running in our warehouse. We do this to continue learning about tumbling rough, tumbling supplies and the machines used to make 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 will sell you a rock tumbler 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. If you have questions, they don't have detailed answers on their website. A lot of people who sell rock tumblers and rock tumbling supplies have never operated a tumbler.

We aren't like that!

We have spent thousands of hours over the past 20 years writing the internet's largest rock tumbling library. If you have a question about rock tumbling, our library probably has the answer. It is loaded with articles that will help you understand rocks, understand tumblers, and improve your rock tumbling results.

Every article in our library has been written by someone who has deep knowedge about rocks, minerals, and gem materials. Our staff has also prepared every article about rocks, minerals and gems that is published on Those articles are read by over a million people every month.

The tumblers we are running 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 from 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 or meet with visitors at our office.

Holiday Shipping Information

Orders placed after 12:00 noon eastern time on Thursday, December 17th, 2020 may not arrive in time for Christmas unless you order Express Shipping. We are located in Pennsylvania, and deliveries to western states, Alaska, and Hawaii require five or six business days by standard shipping. Rock tumblers and tumbling supplies are heavy packages and move slowly.

The map above shows normal shipping times. Holiday shipping WILL take longer.

Please Note: This year, mail service may experience additional delays due to the COVID-19 pandemic. Although we pack and ship orders promptly, we have no control over package delivery services. We cannot guarantee that any package will arrive by a particular date - even if the order was placed before December 17.

We recommend placing your order as early as possible for best results.

We ship by United States Mail, FedEx Ground and FedEx Home Delivery to addresses within the United States. We process orders Monday through Friday. Orders placed through our website usually ship the same day (if received by noon eastern time) or the following business day if the address that you provided is accepted by the U.S. Postal Service (and if rare internet, power or other unforseen problems do not interfere). We do not ship on Saturday, Sunday or U.S. Postal Service holidays.

Everything that can be purchased from our website is in stock and ready for prompt shipment. If you see an "add to cart" button on our website, we almost always have that item in stock and ready for immediate shipment. Rarely, a customer will order more items than we have in stock and we will notify you promptly. If we encounter any problem while filling your order, we will contact you by email or phone. Orders received before noon (eastern time) on a business day usually ship the same day.

If you request "USA Standard Shipping" your order should arrive between 2 and 6 business days after it is placed. If you request "USA Express Shipping" your order should arrive between 1 and 3 business days after it is placed. These shipping times are based upon U.S. Postal Service and FedEx guidance. USPS and FedEx are very good at meeting these delivery times, but sometimes mechanical, weather or other problems will delay a package.

Rock Identification

It is very difficult to identify rocks from photographs because the observer cannot 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.
