ANTIQUE ART DECO TIFFANY & CO 18K White Gold 2.30ct Aquamarine & Diamond Pendant

This exquisite pendant represents the pinnacle of American Art Deco design, crafted by the legendary house of Tiffany & Co. during the 1920s or 1930s. The Art Deco movement was defined by a departure from the flowing lines of the Art Nouveau period, embracing instead a bold, architectural geometry and crisp, linear elegance. Tiffany & Co. mastered this aesthetic, frequently utilizing 18-karat white gold—a metal alloy that gained immense popularity during this era—to provide a bright, structurally resilient backdrop that enhanced the brilliance of the diamonds.

During this period, step-cut aquamarines were highly sought after by elite jewelers for their crystalline transparency and icy, vibrant blue hues. The geometric square cut of this specific 2.3-carat aquamarine perfectly embodies the era’s fascination with symmetry and clean lines, while the diamond-set articulated bail adds a subtle, luxurious contrast. This pendant is a timeless artifact of New York’s high society during the Jazz Age.
