Dinosaur Bone Rings
Where is it from?
Non-gem grade dinosaur bones can be found in many places all over the world. The highly agatized, uniquely patterned dinosaur bone used in our rings is found in the Four Corners region in the United States where Arizona, New Mexico, Utah and Colorado meet. The bulk of the dinosaur bone used in our rings were found in this area.
How is it formed?
Agatized dinosaur bone is a unique fossil where the original fossilized bone, typically permineralized with calcite, has been re-mineralized, or replaced, with silica-type compounds. This requires a particular type of environment, referred to as an aqueous intrusion, to replace the calcite in the original fossils with silicates. For an aqueous intrusion to occur, local strata layers must be uplifted during tertiary intrusions so that silica-rich, superheated groundwater can flood these layers and force water and aqueous solutions into the microporous fossilized bone. It is this rare process that transpired on the Colorado Plateau 35 million years ago that created the beautifully patterned agatized dinosaur bone now used in our rings.
