These incredibly unique cabochons formed from a portion of fossilized Ammonite. This is a fairly rare occurrence where the original Ammonite molecules are replaced by Pyrite. Technically, this is known as Pyrite pseudomorph after Ammonite. Regardless these cabochons are absolutely stunning. There are various shades of brown, beige, black, tan and white. Throughout many of the pieces are swirls and pockets of Pyrite druzy.
