The motive presents the fascinating natural spectacle, whose iridescent colors are reflected between ice floes in the Arctic Ocean. The design is completed by two seals that appear to be watching the spectacle and the inscription “MOTHER OF PEARL CLOUDS”.

Mother-of-pearl clouds are also known as “polar stratospheric clouds” and can only form at extremely low temperatures of less than -78°C. The characteristic color spectrum becomes visible when water droplets in the stratosphere - the layer of air above the troposphere - turn into tiny ice crystals that refract the sunlight.
