1 pound of cut petrified wood from South Dakota. All of these pieces have been cut on both sides which makes a very easy and satisfying tumbling outcome. No need to do multiple rough grind steps as the cut faces are already smooth. This material is very hard and will take a brilliant polish. Order multiple of this item if more pounds are desired. There is also a 5 pound quantity available for a lower price per pound. The picture is a representative sample of the material and is pictured dry and wet.
