6.9" Carey Plume Agate Slab - Carey Ranch, Oregon

Carey Ranch Plume Agate is an agate formation mined from the Carey family ranch near Prineville, Oregon. The first documented find of this agate was a small find that had weathered out from a small volcanic cone. Following some exploring, the outcrop of this agate formation was found and mining began. After years of dirt and rock removal from this volcanic cone, only a large pit remains in its place. This location is now depleted, producing very little if any of these beautiful plume agate specimens. Consequently, Carey Ranch Plume Agate is now considered "extinct" and the only specimens found on the market are from old collections.
