Alot of the dinosaur bone that is found today is not fit for jewelry. This is not fractured or dull in color. This is rare  gem grade. I've had this bone for 30 years and finally cut it. It came from an area that is now Dinosaur National Monument and you can no longer collect there. I seen some dinosaur bone that came from this area that is now in the Smithsonian. It was collected by Mr. and. Mrs. Evans who have both passed. I seen their private collection. It was breathtaking. If you ever get a chance check out the dinosaur bone at the Smithsonian. You will see what I'm talking about.
