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! Just look at this beauty under the black light too! The blue and white natural swirl of colors is just stunning! Thundereggs pair nicely with our Orthoceras Towers or our Splash Copper!!
