Core Rock Bookends 6

Core Rock Bookends approximately 4" in diameter and 5.5 inches high from the San Andres formation located 4,000 feet below the surface. This rock is estimated at being 210 million years old. Collectable I have not made a pair of bookends made from Anhydrate rock like this in a while. That is how valuable they are. Do not wait long on this pair, or they will be gone.
