This is an absolutely stunning specimen of an Irridescent Ammonite from the Cretaceous of Madagascar. This 3-dimensional ammonite has been removed from the surrounding matrix and the outer shell polished to reveal its natural color. The most collectible feature of this ammonite is the natural rainbow iridescence preserved on the both sides of the ammonite! The color is outstanding and is as striking as the photo shows! The completeness of the ammonite and the incredible rainbow color make this a highly collectible ammonite specimen.
