9.5" Polished Dinosaur Bone (Gembone) Vertebra - New Mexico

This is a partial, dinosaur vertebra from the Morrison Formation preserved in very vibrantly colored gembone. One side has been cut and polished to reveal very large red/pink cells preserved in colorful agate. The partial vertebra measures 9.5 x 4.5 x 3.5"

Nearly all of the gembone you see in from either Colorado or Utah, but this material we just acquired is from New Mexico.

About Gembone

Dinosaur gembone (agatized dinosaur bone) forms when the porous structure of dinosaur bone is replaced by silica-rich minerals like agate, chalcedony, or jasper. This preserves the bone’s internal cell patterns, creating striking, web-like textures visible when polished.

Most gembone comes from the Late Jurassic Morrison Formation of Utah and Colorado and can display vivid reds, browns, purples, blacks, or blues—depending on the minerals involved. Highly valued by collectors, jewelers, and lapidary artists, each piece is unique, offering a beautiful and tangible link to prehistoric life.
