I would never profess to be any kind of gemologist - I find new specimens all the time. I've had this sample for years - it was sold to me as dinosaur poop - I also purchased some bone slabs at the same time and will try to find those and list. This piece weighs 1.4 ounces. It measures 4" wide and 2.5" tall - very heavy for the size. Please view all the pictures and make your own decision.
