Ammonite #11(1181) Placenticeras costatum. Measures approximately 38.6 cm. (15.25″) in diameter. This ammonite displays excellent shape and amazingly bright colours on both sides. That ranges from burgundies, reds, oranges, golds, greens and some of the rare blue as well as some purple on the one side. Then mostly burgundies, reds, oranges, golds and greens on the other. There are even tubercles that are visible along the inner ring. This ammonite comes from the top of the Bearpaw formation at the Korite mine. Only in one small area of North America does one find this brilliant gemstone. Over millions of years, the nacre of the ammonite’s shell has been transformed to take on this wild range of iridescent colouring. It comes with a wood display stand and a certificate of authenticity. For international shipping, all customs paperwork is included. This specimen is registered with the Government of Canada and leaves the country with all the required permits and documentation.
