A Thunderegg is formed within Rhyolite volcanic ash layers under significant pressure and heat creating unique and beautiful 3D like patterns. Contains deposits of chalcedony, agate, quartz, jasper and opal. Stunning!!! 3/4 lb 3.5" x 3" x 1.5" Discovered by my friend, Jack Daggert on his own 50 acre property in Oregon, he cut and expertly hand polished this himself.
