"Tumbler rough" is the name used for rock that is suitable for use in a rock tumbler. Agates, jaspers, quartz and many other rocks can be processed in a tumbler to produce rounded gemstones with a very high polish. We offer several types of rough that are sized for the beginner to produce great finished stones.
Rock tumbling "grit" is a silicon carbide powder that is much harder than the types of rocks that are commonly tumbled. Coarse grit is used to shape the rocks then progressively finer grits are used to smooth their surface and prepare them for polishing.
Fine grit (also known as pre-polish) is a 500F grit silicon carbide powder that is used to remove the scratches left by medium grit in step two of the tumbling process. TXP polish is an aluminum oxide powder that brings hard materials such as agate, jasper and quartz to a bright, shiny finish.
Rock tumbling media can significantly improve the results of your tumbling. Tumbling media has three basic functions: 1) Deliver grit to hard-to-reach rock surfaces; 2) A filler when tumbling a partial load of rock; 3) To cushion fragile rock materials during the tumbling process.
Our rock tumbler refill kits include all of the rough rock, grit and polish that you will need to produce one barrel of tumbled stones in a small hobbyist rock tumbler. There is no need to purchase mulitple items. There is no need to measure out grit or polish - we send them to you in pre-measured bags.
There are very few places where you can learn how to tumble polish rocks from an expert. Without that you will make a lot of mistakes and spend lots of time and money producing less than excellent results. If you are just getting started read this book and you will be off to a great start.
We offer a variety of tools that are useful for collecting rocks. Rock hammers, crack hammers, chisels, gold pans, hand lenses and eye protection.
We offer a great selection of rock, gem and mineral books and maps. There are rockhounding books, gem trail books and gold, gem and mineral maps for many western states. Also available are fee mining guides for eastern and western U.S. along with regional gem and mineral guides for the northeast, southeast, northwest and southwest U.S. We also have general books for learning about rocks, minerals and gemstones.
