An American Art Nouveau 18 karat gold stick pin with enameling and opal by Marcus & Co. The stick pin has a cabochon opal surrounded with four enamel side sections decorated with gold relief arabesque designs. During the first decade of the Twentieth century the firm Marcus & Co. offered a variety of Revivalist-style jewelry. Egyptian-inspired pieces along with Renaissance Revival and Mughal style were created. The venerable firm of Marcus & Co. was established in 1892 by William, Herman and George Elder Marcus, with a shop in New York. The firm distinguished itself as an early proponent of the Art Nouveau style in America, of which this ring is an exquisite example. During the Art Deco period of the 1920's, the firm continued producing fine jewels in this new style and expanded with branches in London, Paris, and Palm Beach.

A French Art Deco platinum ring with peridot and diamonds by René Boivin. The ring centers on a cushion-cut peridot with an approximate weight of 3.25 carats, surrounded by 60 pavé set round-cut diamonds with an approximate total weight of 3.60 carats. With Certificate of Authenticity from Madame Françoise Cailles, expert for Boivin. René Boivin has been one of the most significant jewelry houses for the best part of a century since its late 19th Century beginnings under its founder Jules René Boivin. The significant legacy is due in no small measure to Jeanne Boivin, who took over her husband's business after his death in 1917. Rather than wholly embracing the Art Deco trend that engulfed the rest of the French jewelry world in the late 1920s and early 1930s, she was also inspired by the exoticism that was enchanting the likes of Picasso and Paul Gauguin. Remaining close to the design greats such as Sandoz or Fouquet, she added her own feminine eye to the movement's ideals with the help of Suzanne Belperron from 1921 to 1932. The Boivin house would go on to create many spectacular jewels famously inspired by nature and sea life. A similar ring is pictured in "Rene Boivin Jeweller", by Françoise Cailles, Quartet Books, 1994. Ring size 4; this ring can be sized.
