7.8" Polished Dinosaur Bone (Gembone) Vertebra Section

This is a 7.8" wide section of dinosaur bone from the Morrison Formation of either Utah or Colorado. One side has been cut flat and polished to a glossy finish which allows for the beautiful internal cell structure to be seen.

It is accompanied by an acrylic/metal display stand to assist with presentation.

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.
