Polychrome Jasper Tumbling Rough



Size: mostly 3/8" to 1 1/2 inch pieces



They call this material "polychrome" because it is a rock with many colors. It is mostly reds and pinks, mixed with brown, orange, white, gray and a few tinges of other colors. It takes a great polish and rounds well in a rotary tumbler.

This mix was crushed and sized to work great for the beginner. It has a range of particle sizes from approximately 3/8" (9 mm) to 1 1/2"" (38 mm) and should require little to no preparation. We ran straight rough without using any ceramic media. We obtained great polishing results using the inexpensive TXP aluminum oxide polish.

We started polishing about four pounds the day it arrived. You can see our polished stones in the photo below and our tumbling procedure is below the photo.

EASY Rock Tumbling Recipe:


Polychrome Jasper (3/8 to 1 1/2 inches)



This polychrome jasper has been crushed and sized to perform well in small rotary tumblers such as the Thumler's MP-1, A-R1, and A-R2. The size range gives the material a good tumbling action and eliminates the need for ceramic media. Our EASY Rock Tumbling Recipe works well for rough that has a Mohs hardness of 7 and has been crushed to a variety of particle sizes under about 1 1/2 inches.


Recipe for Rotary Tumbling

Tumbling Recipe for easy crushed rough


Coarse Grit Step:
Fill your tumbler barrel about 2/3 full of rough. Then add 2 tablespoons of coarse (60/90) grit per pound of material in the barrel. Add water to just below the top of the rocks. Run the material in coarse grit for 1-2 weeks. One week in coarse grit will give you good results. However, we feel that two weeks in coarse grit gives you much better results.

At the end of all steps in the rock tumbling process, make sure to clean your rocks and barrel to reduce the chance of coarser grit contaminating the finer grit steps..

Medium Grit Step:
Put your cleaned rough back into the barrel. Then add 2 tablespoons of medium (150/220) grit per pound of material in the barrel. Add water until it is just below the top of the rocks. Let it tumble for one week.

Do not pour tumbling mud down the drain
Barrel slurry dumped down the drain will harden like concrete.
Fine Grit Step:
After clean-up, put the rocks back into the barrel using 2 tablespoons of fine grit per pound of material. Again add water to just a little below the top of the rocks. Tumble for one week. The rocks should now be smooth and possibly starting to get a slight luster.

Polish Step:
IMPORTANT: Make sure that your barrel and rough have been cleaned thoroughly. Any grit carried over from a previous step will likely ruin your polish. Place the rough in the barrel with two tablespoons of TXP polish for each pound of material in the barrel. Add enough water to almost cover the rocks and let it tumble for one week.

Burnish If Needed:
Jasper, agate and petrified wood usually take a great polish. However, burnishing this material after the polish step can often improve the shininess of the finished stones. If you would like to try burnishing to see if it improves the look of your polished stones full burnishing instructions can be found here.
