Condition Notes: This spectacular necklace by Mauboussin highlights the French maison’s keen eye for color, pattern, and design. Crafted in 18k yellow gold, the piece is composed of interlocking twisted links that alternate gracefully between vibrant turquoise and pavé-set diamonds. Each turquoise section is seamlessly set into the gold framework with closed backings and displays a vivid robin’s egg blue hue.
The necklace is faintly engraved "Mauboussin 48404" near an unidentified French maker’s mark. The turquoise has not been tested for origin of color or treatment, however, under magnification areas of matrix (natural host rock from formation) are visible.
Mauboussin: It was Paris 1827, the year when the House of Mauboussin opened. The firm specialized in highly stylized architectural jewels set with precious gems of vibrant hue, accented by sparkling white diamonds. They exhibited at the 1925 International Exhibition des Arts Decoratifs in Paris, and won the grand prize. Georges Mauboussin believed that jewelry should reflect the wearer's personality with a jeweled accent. Its Reflection series struck a chord with socialites and celebrities, such as Marlene Dietrich, who flocked to Mauboussin. The company opened offices in Buenos Aires and London prior to New York, in 1929. The ill-timed opening of their New York branch coincided with the stock market crash the same year. A weakened Mauboussin merged with Trabert & Hoeffer, Inc.
