Edwardian to Art Deco Gold & Platinum Calibre Ruby Diamond Geometric Stick Pin

Late Edwardian to Art Deco Gold & Platinum Calibre Ruby Diamond Geometric Stick Pin

This refined stick pin captures a pivotal moment in jewelry history, marking the transition from the graceful delicacy of the Edwardian era to the structured elegance of early Art Deco. Crafted in gold with platinum-topped elements, the design reflects both technical precision and artistic evolution.

At its center is a bold geometric composition reminiscent of a stylized Greek key or stepped architectural motif. The strong symmetry and clean lines signal the modern direction jewelry was taking in the 1910s, while fine milgrain detailing and platinum settings preserve the refinement associated with Edwardian craftsmanship.

The border is set with precisely cut calibre rubies, carefully fitted to follow the angular outline — a technically demanding technique requiring exceptional skill. Their vivid red tone contrasts beautifully with the brilliance of the old-cut diamonds, mounted in platinum to enhance light and definition. The result is a piece that feels both architectural and elegant.

Created circa 1910–1920, this jewel represents the shift toward modern geometry while retaining the delicacy of earlier design. A sophisticated and highly collectible example of early 20th-century transitional jewelry.
