Located in New York, NY
A Whimsical Nod to the Jazz Age Embrace the elegance and playful spirit of the Art Deco era with this charming platinum stick pin, intricately designed in the form of a duck. Lovingly adorned with small round diamonds and set with a ruby eye, this piece blends humor, artistry, and timeless sophistication. Whether worn on a lapel, hat, or scarf, it will make an eye-catching statement that sparks conversation. Exquisite Details & Design Duck Motif Sculpted to depict a duck in graceful profile, the stick pin’s bird figure showcases the streamlined geometry and refined artistry characteristic of Art Deco design. Diamond Accents Small round diamonds accent the duck’s body, creating a captivating interplay of light along the polished platinum. These gems not only add sparkle but also underscore the piece’s fine craftsmanship. Ruby Eye For a touch of warmth and color, a small ruby is set to form the duck’s eye, providing a subtle yet striking contrast to the duck’s diamond-clad body. Premium Platinum Setting Renowned for its strength, durability, and white luster, platinum was a hallmark of luxurious Art Deco jewelry. The metal’s cool tone highlights the brilliance of both diamonds and ruby, ensuring a refined, classic finish. Dimensions & Origin Length: Approximately 2.25 inches Width: Approximately 0.90 inches at the widest point (duck motif) Circa: Early 20th Century Origin: Continental (European) Its compact size offers versatility—easily pinned to lapels, hats, or scarves—while maintaining a clear and eye-catching presence. Why Choose This Art Deco Stick Pin? Historic Allure: Authentic Art Deco pieces carry the distinctive design echoes of the 1920s–1930s, offering collectors and enthusiasts a true glimpse into the era’s aesthetic brilliance. Rare & Whimsical Design: The duck motif, complete with diamond feathers and a ruby eye, presents a conversation-worthy twist on classic Art Deco geometry. Versatile Styling: Stick pins add a polished accent to both casual and formal ensembles, reflecting individual personality while remaining tasteful and chic. Care & Maintenance Cleaning: Gently wipe the platinum and gemstones with a soft, lint-free cloth after each wear. Avoid harsh chemicals; if deeper cleaning is needed, a mild jewelry solution safe for platinum and precious gems is recommended. Storage: Store in a padded jewelry box or soft pouch, ensuring the pin remains separated from other pieces to prevent scratches or tangling. Delight in the playful charm and refined elegance of this Art Deco Platinum Duck...
