An extraordinary Art Deco platinum brooch suite, circa 1930, showcasing the geometric precision and luxury that defined the era. Composed of three interlocking segments, this design allows for versatile wear — each segment can be worn independently or combined into one striking statement piece.

The brooch features three sleek black onyx plaques, paired with 166 round brilliant-cut diamonds totaling approximately 9.24 carats, and 81 single-cut diamonds adding an additional 1.62 carats. The streamlined fan motif — with radiating diamond-set channels and arched forms — exemplifies the bold sophistication of 1930s Deco jewelry.

A rare and collectible piece from the height of the Art Deco movement, blending sharp contrast, innovation, and exceptional craftsmanship.
