Collection: Iridescent ammonites
These amazing ammonites come from Somerset in the UK, close to the Jurassic Coast. They display an incredible range of iridescent colours that change when the light or viewing angle changes. All the colours of the rainbow can be found in these shells, from vivid reds to deep blues, greens and purples.
