Taking inspiration from the opulent gilded interiors of the Opéra de Paris, the Phantom's side plates are meticulously finished by the skilled master gilders at Ateliers Gohard. Employing time-honored methods, each gold leaf is meticulously applied by hand, resulting in a unique patina. These heritage techniques require impeccable precision, as once the leaf is affixed, it becomes permanent. The side plates bear the signature Phantom I 108 dB Opéra de Paris | Devialet and are adorned with Moon Gold, a precious and stainless palladium-yellow gold alloy.
