Black Spiderweb Dinosaur Bone Earrings

This is a beautiful set of earrings hand-crafted from 150 million year old, agatized dinosaur bone by master stone craftsman, Kenneth Kolb. The amazingly agatized cell structure of the bone creates a colorful, spiderweb like appearance. This one of a kind set if earrings is 1-1/2" x 9/16" x 3/16" with silver findings. Less than 1% of all gem-grade dinosaur bone is of the quality used in this pair and it took over 6 hours of work to complete.

We also have a matching pendant for sale separately.

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

Agatized or agate replaced dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone, typically permineralized with calcite, has been re-mineralized with silica-type compounds such as agate, jasper, chalcedony, or opal.

In a unique and isolated circumstance, the strata on the Colorado Plateau were uplifted during the tertiary intrusions about 35 million years ago when the San Rafael Swell and the La Sals, Henry, and Abajo Mountains were formed. As these ranges were forming, local strata layers were flooded with silica-rich, superheated groundwater. This provided the appropriate environment to start this calcite-silicate replacement in the original fossils. The most prolific layers of gem bone come from the Morrison Formation, which is late Jurassic in age.
