Polished Fossil Dinosaur Bone (Gembone) Earrings
This is a beautiful pair of earrings made from 150 million year old agatized fossil dinosaur bone, commonly known as Gembone. The internal cell structure of the dinosaur bone can clearly be seen.
The bone would have likely been from one of the large Sauropod dinosaurs in the Morrison Formation such as Diplodocus or Camarasaurus, as theropod bones such as Allosaurus are hollow and typically not solid enough to cab. Isolated, and fragmented pieces of bone are used are used for making jewelry. While small, broken pieces of bone are vey common in some areas of the Morrison Formation, very little of it is agatized and has good enamel color quality to be considered "Gembone"

About Dinosaur Gembone
Dinosaur gembone, also known as agatized or fossilized dinosaur bone, is a rare and highly prized material formed when the porous structure of dinosaur bone is replaced by silica-rich minerals such as agate, chalcedony, or jasper over millions of years. This fossilization process preserves the intricate internal cell patterns of the original bone, which are often visible as vibrant, web-like structures under the polished surface.
Gembone is typically found in the Morrison Formation of the American West, especially in Utah and Colorado, where Late Jurassic dinosaur remains are common. The resulting stones can display a wide range of striking colors—including reds, browns, purples, blacks, and blues—depending on the specific minerals present during fossilization.
Highly sought after by collectors, lapidary artists, and jewelers, dinosaur gembone is both a geological wonder and a tangible connection to the prehistoric past. Each piece is completely unique, with its own natural patterning and coloration shaped by ancient time and mineral-rich waters.
