🌿 Mossy Thunderegg Pair — Old Stock Old stock Oregon mossy thunderegg pair, cut and polished by me! These have gorgeous earthy tones with translucent chalcedony and intricate mossy mineral inclusions. No two thundereggs are ever quite alike! Oregon designated the thunderegg as its official state rock in 1965. These unique formations developed millions of years ago in ancient volcanic ash beds. Gas and steam pockets created cavities within cooling rhyolite, which were later filled by mineral-rich groundwater, forming agate, chalcedony, jasper, quartz, and other beautiful internal patterns. ✨ Old stock material ✨ Pair from the same thunderegg ✨ Cut & polished by me ✨ Natural mossy inclusions & earthy colors A beautiful piece of Oregon geology for collectors, rockhounds, or anyone who loves one-of-a-kind lapidary material! 🌲🪨
