An exquisite expression of Art Deco design, this platinum and diamond brooch captures the architectural elegance and bold geometry of the 1920s.

Crafted circa 1925–1930, this striking piece features an intricate openwork design with strong symmetry and layered dimension. The composition is centered around a brilliant old-cut diamond, surrounded by a meticulously arranged field of additional diamonds, all set within a finely pierced framework. Distinctive Greek Key motifs and geometric elements reflect the influence of classical design reimagined through the modern lens of the Jazz Age.

Set with approximately 2.75 carats total weight of diamonds, including a combination of old European cut and single-cut stones, the brooch displays a soft, romantic brilliance characteristic of antique diamonds. Fine milgrain detailing throughout enhances its texture and craftsmanship.

Designed with versatility in mind, the piece includes a discreet convertible bail, allowing it to be worn both as a brooch or as an elegant pendant—perfect for modern styling.

A true statement piece, rich in history and artistry, this brooch embodies the timeless sophistication of the Art Deco era.
