Since 1922 Black and white jewels were considered very elegant and distinctive for evenings. Rock crystal, pearls, Onyx and diamonds were mixed in very delicate platinum settings. Since the Art Deco Exposition in 1925,  jewels became definetly polychrome with jade or coral details. 

Intorno al 1922 i gioielli in bianco e nero erano molto in voga, considerati appropriati ed eleganti per la sera. Cristallo di rocca, perle, diamanti e onice erano combinati in delicate montature in platino. A partire dall'Exposition Internationale des Arts Décoratifs del 1925 i gioielli diventano decisamente policromi ed al bianco e nero si aggiunsero elementi colorati creati in giada e corallo.
