Ammolite is a fossil gemstone composed of ammonite shells that have undergone a process of mineralization, preserving and intensifying the natural aragonite in the shell, which produces the vivid iridescent sheen. It is found almost exclusively in the Bearpaw Formation of southern Alberta, Canada.

This pendant necklace features a 0.657" ammolite gemstone fossil with a beautiful green shimmer. The ammolite is displayed in a custom-made, gold bezel which is strung on an oval chain. The chain measures 18 inches.
