Diancie is a gray, sylph-like Pokémon with a white chest and arms resembling a dress. Its headdress consists of pink crystals, four short ones cresting along top pointing upward and two long ones on either side of its head pointing downward, with a diamond-cut centerpiece framed by its slim gray ears. A smaller pink crystal is also embedded in the back of its head and a gold nugget is embedded in its forehead. Its eyes are red with pink irises. A gold crescent circles its neck, with the ends joined by a rhomboid gem. Its lower body resembles a large oblong chunk of stone, with a large pink crystal protruding from it.
