This Art Deco onyx and diamond ring was made by French jewellery house René Boivin.
Rather than fully embracing the Art Deco trend that engulfed much of the French jewellery world in the late 1920s and early ’30s, the firm also developed a taste for exotic themes, colours and materials. This was in no small part down to Boivin’s wife Jeanne Poiret, a jeweller in her own right, who assumed control of the business when he died in 1917 and steered it through its four most prosperous decades.
The ring is guided at $10,000-15,000 in a 400-lot sale of diamonds, coloured stones, and antique and period jewellery at Skinner of Boston on September 25.
