Lot 151 – 18k Gold, Molded Glassand Enamel Medusa and Snake Ring, by René Lalique

However, the most significant feature of the Sotheby’s New York, Autumn “Important Jewels” Sale will be the appearance of historically important, exquisite turn-of-the-20th-century designs by René Lalique and Louis Comfort Tiffany. René Lalique (1860-1945) regarded as the father of Art Nouveau design in jewelry grew up in the northeastern French town of Aÿ-en-Champagne, where his exposure to the natural fauna and flora of the countryside had a lasting impact on his life, and inspired him to adopt animal and plant motifs in his creative designs as a professional jewelry designer. He moved to Paris as a young jewelry artisan, where he worked as a freelance jeweler for firms like Boucheron and Maison Vever. In 1887, at the age of 27, Lalique started his own jewelry business that gave him the freedom to reveal the true depth of his artistry. He chose materials for their power, light and color and borrowing techniques from other decorative arts, brought the plants and animals of his childhood into his work as a designer. He fearlessly combined glass, enamel and semi-precious stones with precious metals like gold, creating Art Nouveau pieces that included stunning flora and fauna designs. Sarah Bernhardt (1844-1923), the French actress was a patron of Lalique’s work. On two occasions Lalique designed two serpent-form jewels for Sarah Bernhardt to be used in her role as the formidable Empress Theodora of Byzantine. Lalique was so fond of this motif that around the year 1900 he created a Medusa-inspired ring, featuring a blue glass portrait of Medusa framed by a curving snake,with textured gold scales, accented by green and blue enamel. The serene expression on the blue molded glass face of the Medusa,seem to be at odds with a coiled serpent on its head, poised to strike., with its mouth open and fangs on the upper jaw.
