Who Are You Doing Business With?



You are buying from people who have done a lot of rock tumbling. We probably have several rock tumblers running in our warehouse while you are reading this. Every member of our staff knows how to operate a rock tumbler and has produced nice tumbled stones.

Hobart King has been running rock tumblers for over fifty years. He has a PhD in geology and spent part of his professional career evaluating the physical properties of rocks and minerals to determine their suitability for manufacturing, construction, and other industrial processes. He has applied that knowledge to rock tumbling. He also holds a Graduate Gemologist diploma from the Gemological Institute of America. He knows a lot about rocks and a lot about gems. He has written all of the articles about rocks, minerals, and gems that are published on Geology.com.

Adam Rittenhouse has been running rock tumblers for about three years. In those three years he has been running multiple tumblers every day. He has tumbled (and kept detailed records) for hundreds of batches of rocks, of all kinds, using many types and brands of rotary and vibratory tumblers. He tests every tumbling rough that we sell and every tumbling rough that we decide not to sell. If he can't polish it, we don't sell it.

Angela King wrote what we believe is the earliest collection of rock tumbling articles that became very popular on the internet. They were published on Geology.com, and hundreds of people viewed those articles every day. Those articles have been incorporated into the RockTumbler.com library. Angela has an Applied Jewelry Professional diploma from the Gemological Institute of America and is the webmaster for both RockTumbler.com and Geology.com.

From all of this tumbling, we have learned which products we can recommend and sell with confidence. We don't want to sell you a product that does not work. We will not sell you a product that we will not use in our own tumbling! Most of the tumblers and supplies sold on this website are being used by us every day.


Our Rock Tumbling Library



We have spent thousands of hours over the past 20 years writing an extensive 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 and edited by people who have a deep knowledge about rocks, minerals, and gem materials. Our staff has also prepared every article about rocks, minerals and gems that is published on Geology.com. Those articles are read by over a million people every month.


Detailed and Accurate Product Descriptions



Many websites that sell rock tumblers do not have detailed product descriptions or articles that tell you how to decide what to purchase and how to use it.

All of the rock tumblers and other products that we sell have retail descriptions written by people who have used those items many, many times. We try to answer ALL of the important questions that we have heard about those products. We also make a special effort to answer the questions that people don't usually think about asking - even when those questions might be deal-breakers for the purchase.

A lot of people who sell rock tumblers and rock tumbling supplies have never operated a tumbler. That's why their product descriptions are prattle, puny, or inaccurate.

When we buy something, we like to buy from someone who knows the product. That's what you get here. The tumblers we are running

RockTumbler.com 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 stones

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.

Warranty Service and Replacements



Every new rock tumbler that we sell is covered by a warranty or guarantee. These warranties and guarantees are made by the manufacturers (we are a separate company who retails their products). The manufacturers are responsible for providing all services and replacements under their warranties and guarantees.

If you need warranty or guarantee assistance for a Thumler's Tumbler or a Lot-O-Tumbler, you can find copies of the warranty documents currently shipped with their tumblers here. Please read their warranty or guarantee and contact them if your situation qualifies for warranty assistance.

We have been doing business with Thumler's Tumblers and Lot-O-Tumblers since 2009 and have sold thousands of their tumblers. We have never heard of a single situation where we feel that they failed to meet their warranty or guarantee promises. We believe that you can buy their products with great confidence.

If you have another brand of rock tumbler, you can probably find manufacturer contact information in our list of rock tumbler manufacturers.

Rock, Mineral and Gem Identification



If you are trying to identify tumbled stones purchased from this website, we have a large collection of tumbled stone photos that might be helpful. Although comparing your stone to a photograph is not an ideal way to do identification, many types of tumbled stones have a very distinctive appearance. The photos in our collection often help people determine the identity of tumbled stones sold on this website. For stones purchased from other sources, the seller should be able to help you.

If you are trying to identify rocks and minerals found in the field, the best people to help you 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 traveling to them to avoid disappointment.

We have authored over 300 articles about rocks, minerals, and gems and published them on Geology.com. They are one of the internet's largest and most popular collections of articles about Earth materials. You can find them here: rocks, minerals, gems.
