A Thunderegg is often mistaken for a mineral or geode. Thundereggs are more solid than geodes. Inside Thundereggs you will find chalcedony or agate.
This particular specimen has been split and polished to show off the gorgeous minerals inside! The blue and white natural swirl of colors is just stunning! Thundereggs pair nicely with our Orthoceras Spheres and Trilobites!!
