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 gorgeous veins of Chalcedony! The natural fluorescence in these Thundereggs cause them to glow under the black light. Just look at the beauty!!
Thundereggs pair nicely with our Grape Agate!
