Extra Large Double Thunder Egg Slab


This is a very large and thick slab of a double thunder egg I dug at the Polka Dot mine in Central Oregon. This piece is fully polished on one side.  It has one stalactite that is connected on both ends visible and the core has agate and additional mineral coatings with some being U reactive. The shell is beautiful picture rhyolite that I have slightly rounded the edge on to help prevent chipping during display.
