Madagascar Petrified Wood

Selected and prepared for making tumbled stones in a rock tumbler.

This photo shows a two-pound sample of Madagascar Petrified Wood tumbling rough. The rocks were photographed wet to show their potential polished color. If you look closely, you can recognize evidence of wood grain in some of the pieces. Please click on the image for a larger view.

Adam Rittenhouse of our staff tumbled a couple batches of this rough, and here are some of his tumbled stones. We are very pleased with the color of the stones and their bright polished luster.

What Is Madagascar Petrified Wood?

This is a beautiful petrified wood from a mine on the island nation of Madagascar. It is composed of chalcedony, a microcrystalline variety of quartz, which has a Mohs hardness of seven. It is thoroughly silicified and is well suited for rock tumbling.

Tumbling instructions for this rock

Many pieces of this rough show distinct evidence of wood grain. The color ranges from white to cream to tan, and from red to reddish brown to black. The pieces of rough range between about 1/2 inch to 2 inches in size. This size range works well in small tumblers such as the Thumler's MP-1, Thumler's A-R1, and Thumler's A-R2 rock tumblers.

We have tumbled this petrified wood several times with great results in rotary and vibratory tumblers. It has produced nicely shaped, colorful stones with a very bright polish. You can see wet pieces of rough (made wet to show potential polished color) and some stones that Adam Rittenhouse polished in the photos above.

If you are a beginner at rock tumbling, this is a great tumbling rough for you because no special skills or equipment are needed to produce great results. We believe that if you carefully follow our tumbling instructions at the link below, using quality grit and polish, you will be able to make some nice tumbled stones. Happy Tumbling !

Tumble this rock using our Instructions for Jasper, Agate, and Chalcedony.

Large Ceramic Media

Large ceramic pellets work great as a filler and for delivering grit or polish to difficult-to-reach surfaces. More information...

Small Ceramic Media

Small ceramic pellets work great when you need small material for better tumbling action or to deliver grit or polish to difficult-to-reach surfaces. More information...

Standard Grit Kit

1 pound of each: coarse, medium and fine grit. 8 ounces of TXP polish. This is enough supplies to tumble up to four three-pound barrels of rocks. Save money with a large grit kit.
