Un joaillier raconte à ses enfants l’histoire du diamant. Une mise en perspective existentielle de l’histoire de la pierre précieuse, soutenue par la voix d'un conteur prompt à digresser.
A jelewer tells his children the diamond's history. Next to the story of the diamond size évolution, that moves towards the uniformization by rejecting all impure rock, we see his children grow up and the father's fear of their own uniformization.
