Fiann Smithwick Instagram – An iridescent ammonite from Somerset, UK (Caloceras johnstoni).
These ammonites can show almost all the colours of the rainbow depending on the angle you’re looking at them from. The light is refracted by the layers of the shell, changing the wavelengths of the light reflected back to you. The thickness of the shell determines the colours.
Nature at it’s artistic best!
