This Oregon Blue-Gray Agate Thunderegg Half, measuring 4.5" wide, 3.8" tall, and 1.6" thick and weighing 1.32 lbs, reveals a world of quiet beauty when split open. The polished interior glows with soft blue-gray chalcedony—broad translucent areas and subtle banding flowing across the face like frozen water—while the unfinished exterior remains raw and rugged, a striking contrast that tells the story of how these treasures form within host rock.
Sourced from north-central Oregon's legendary thunderegg country, this piece carries the geological character of a region known for these remarkable nodules. The earthy matrix material preserved through the center grounds the piece, connecting you directly to the ancient formations that created it.
