Founded in the early 1920s by Swiss‑born jeweller Arnold Ostertag, the House of Ostertag quickly established itself on Paris’s Place Vendôme, operating alongside Cartier, Boucheron and Van Cleef & Arpels. Ostertag became renowned for exquisitely crafted Art Deco jewels distinguished by bold geometry, refined platinum work, and a vivid palette of carved coloured stones.
