Agatized dinosaur bone occurs from permineralization, a process whereby minerals rich in silicon dioxide
fill the spaces within and between the cellular structures of the bone. Agatized fossilized dinosaur bones are
petrified with silica or quartz crystals which gives them their colorful, glassy appearance. This process
preserves the actual cell structure of the once living dinosaur.

The highly agatized and beautifully colored & patterned dinosaur bone known as “gem bone” is almost
exclusively found in the “Four Corners” region of the Colorado Plateau in the USA where the states of
Arizona, New Mexico, Utah, and Colorado meet. The wide variety of colors in agatized dinosaur bone is
caused by minerals such as chlorite, chromium, iron-oxide and manganese that enter the cells during

Unpolished rough rock cabbing slabs of Dinosaur Bone shown here are ready to be cut, shaped, and
polished. These pieces of dinosaur bone are from the Four Corners Region.
