This is a large thunder egg I dug from the Polka Dot Mine north of Madras, Oregon in the canyons near the community of Ashwood. I have shaped this piece into a polished freeform art piece suitable for display or it can be core drilled to the appropriate size for your tubing to make a small to medium fountain and a flat bottom can be cut to sit on. It has a band of translucent agate along with some small chalcedony stalactites and the characteristic picture rhyolite the “canyon rim” thunder eggs are known for.
this piece weighs nearly 3.5 pounds and is 5” wide at the polished face and and 3” deep with a nice open cavity inside.
shipping and packaging is included in the price
