The founders rock in a bag of material that was rough and ready to put into the Rock tumbler. In fact, we are pretty sure this came in the bag of rocks given to you by the people who sell rock tumblers. The stone circle have polished it up although this stone has not taken a shine.

We thought this might be Mookaite Jasper but we have never seen it in this color before. We have also had Mookaite in the store and it has polished. So this alien head remains unidentified.
