Estate 14K White Gold Diamond & Synthetic Blue Sapphire Art Deco Brooch

This Art Deco brooch is crafted in 14 karat white gold and features a geometric, elongated design set with forty-nine old European cut diamonds totaling approximately 2.29 carats, graded G-I color with VS2-I1 clarity. The diamonds are arranged across a structured openwork pattern, accented by twelve synthetic blue sapphires that introduce contrast and definition to the design. Measuring approximately 2.5 inches wide and 15/16 inches tall, the brooch is finished with a classic C catch closure.

Structured and expressive, this diamond and sapphire brooch carries the kind of precision that makes Art Deco design so enduring. The balance of bright diamonds and deep blue accents creates a crisp, architectural look that feels intentional from every angle. It pairs naturally with tailored pieces like a blazer lapel or the neckline of a structured dress, adding definition without feeling overdone. Worn on a silk scarf or pinned at the waist, it brings a sense of collected style that feels both thoughtful and distinctive.

Why Synthetic Sapphires Were Used in Art Deco Jewelry

During the Art Deco period, synthetic sapphires were widely used alongside natural gemstones, not as a substitute but as a deliberate design choice. Advances in gemstone creation allowed for consistent color and clarity, which made them ideal for the precise, geometric patterns that defined the era. Their rich blue tone provided strong contrast against diamonds and white metals, helping to emphasize symmetry and structure. Today, their presence is part of what makes many Art Deco pieces feel authentic to the time, reflecting both the innovation and aesthetic priorities of the period.
