Pyritized dinosaur bone cab ~
Offered here is a large collector's cabochon of pyritized dinosaur bone, cut from a specimen found on the shores of a river in Siberia. The highly prized and extremely RARE material is many millions of years old, a marvelous example of the natural preservation of our earth's ancient, extinct 'thunder lizards'. Nearly every last bit of the once living bone has been replaced with shiny metallic pyrite (and probably marcasite), and the subtle pattern of the darker cell walls is still quite apparent. WOW!!! You definitely won't find many like this; in fact, the handful of cabs I've cut over the years are the only ones I have EVER seen! This beauty has a gracefully curved designer shape, and a bright, gleaming mirror-like polish both front and back.
Size: 56x18mm
Weight: approximately 51 carats
