A study in fluid form and vintage allure. The Seraphina Flat Tubogas Necklace drapes like liquid gold, sculpted from interlocking coils that move with the body. Inspired by mid-century Italian design, its sleek, flat silhouette sits close to the skin—modern yet timeless. Finished with a delicate butterfly clasp for a seamless closure and a touch of refinement.

Wear it alone for understated polish or layer it to build your own story in gold.

Tubogas—Crafted from interlocking gold strips, forming a flexible, hollow tube—bold in appearance yet lightweight by design. Handle with care to preserve its seamless construction, as dents cannot be repaired. Store in its natural shape to prevent stress on the structure.

Enjoy one complimentary repair within six months for any manufacturing defects. Upgrade to our Kinn Concierge Service for extended coverage. Please note: normal variations including normal wear and tear, improper care, storage techniques or third-party modifications do not fall under our warranty.
