Each of these one-of-a-kind dinosaur "gembone" fossils are a rare form of agatized fossil found only on the Colorado Plateau.  The crystalline structure of the agate preserves the cellular formation of the interior of the bone, resulting in the totally unique colors and patters.  The circular pendants are roughly 3/4 of an inch in diameter and are suspended on an 18 inch 14k gold filled ear wire - custom lengths available.
