Agatized Dinosaur Bone "Egg" - Stunning!

This is a stunningly polished "egg" of agatized dinosaur bone, which was hand-crafted by master stone carver, Kenneth Kolb. The beautifully preserved cell structure inside this piece is simply jaw dropping. This sculptured piece is 1" x 1" x 1-1/4" and comes with the pictured metal stand. Gem grade, agatized dinosaur bone with of this high quality is very rare and this was the last egg shaped sculpture currently available from the artist.

This may have come from any of the dinosaurs found in the Morrison Formation including Allosaurus, Apatosaurus, Brachiosaurus, Camarasaurus, Diplodocus, Stegosaurus, and Torvosaurus.

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.
