This incredibly rare 6.5 inch ThunderEgg has a large center of Blue and Red Agate with calcite inclusions.
This Nodule was collected in Oregon in the 1990s, but ThunderEggs this large are no longer seen “in the wild” in those beds. Our Supply of ThunderEggs is created through volcanic activity, so they will not be replenished until there is another large round of explosions.
