The crystal seal of Mani (French: Sceau de Mani), also known as the crystal sealstone of Mani or the Manichean Rock-Crystal Seal, is a crystal stone seal with intaglio busts of three Manichean elect. There is a circle of Syriac writing around the intaglio, which could have been a personal seal used by Mani, the founder of Manichaeism. It is the oldest surviving piece of Manichaean art, and the only piece from Sassanid Mesopotamia. It is now in the collection of the National Library of France in Paris.
