Polished Thunder Egg Half With Heart Shaped Interior

Thunder Egg

Richardson Ranch, Madras, Jefferson County, Oregon, USA

Thunder Eggs are often considered to be solid volcanic geodes but that is technically not correct as a Thunder Egg can result from various nodules other than just a geode. However this beautiful chalcedony filled geode has gorgeous red, blues, and greens to it! Whether it is a geode or not doesn't matter. It's gorgeous!
