Art Nouveau 18K Gold Rose-Cut Diamond Stick Pin

Antique 18K Yellow Gold Diamond Stick Pin

This refined Art Nouveau stick pin is crafted in solid 18K gold, clearly stamped with the 18K hallmark on the reverse, confirming its high gold purity and period authenticity. The circular openwork plaque features a sculptural floral motif, characteristic of Art Nouveau design, accented with rose-cut diamonds set organically within the composition.

The plaque is well proportioned, offering a pleasing presence that is neither small nor oversized, making it both noticeable and elegant when worn. The hand-carved detailing reflects the artisanal techniques of the late 19th to early 20th century, while the diamonds provide subtle brilliance without overpowering the design. The construction and hallmark together indicate a piece made to a high standard, intended as a refined accent rather than overt display.

Elegant and thoughtfully balanced, this stick pin exemplifies the harmony of craftsmanship, precious materials, and artistic expression that defines fine Art Nouveau jewelry.
