The chain that makes simplicity look intentional.
Maillon Serein refines the modern paperclip chain into a slim 2.1 mm silhouette defined by elongated links, polished surfaces and the warm tone of 14K yellow gold. Its clean proportions give the chain enough definition to stand beautifully on its own while keeping it effortless to combine with other necklaces.
Choose the 16 inch length for a close to the neck fit, 18 inches for a classic everyday proportion, 20 inches for a more relaxed neckline or 24 inches for a longer statement. A 7-inch option transforms the same signature link design into a coordinating paperclip bracelet.
The chain is crafted in 14K yellow gold-filled metal, created by bonding a layer of 14K gold to a supporting metal core. Gold-filled jewelry is distinct from solid 14K gold, giving customers a more accessible way to experience the appearance and warmth of yellow gold.
Finished with solid chain construction and a secure lobster clasp, Maillon Serein was designed as an adaptable foundation for everyday jewelry styling, polished enough to wear alone and understated enough to become part of a layered look.

This Paperclip-Style Chain, a standout within 302 Fine Jewelry's Utility Collection, is featured in the September 2021 issues of Harper's Bazaar and Elle magazines.

Gold-Filled
Our gold-filled jewelry refers to a layer of 14K or 18K yellow gold that is soldered or mechanically bonded under heat and pressure to one or more surfaces of a base metal. The gold must be at least ¹⁄₂₀ of the total weight of the piece. This technique offers a significantly thicker layer of gold on the piece compared to other options and offers an appealing balance between cost and quality.

How to Care for Your Jewelry
A little care keeps your Oxfordum pieces looking their best. Follow these simple guidelines.
Solid Gold (10K, 14K, 18K)
- Clean with warm water, a drop of mild soap and a soft brush; rinse and pat dry.
- Remove before swimming in chlorinated pools, cleaning with household chemicals, or heavy work.
- Store pieces separately so harder stones and chains don't scratch softer gold.
Gold Vermeil & Gold-Filled
- Remove before swimming, showering, or exercising.
- Avoid perfume, lotions, and harsh chemicals directly on the piece.
- Store in a cool, dry place — ideally in a pouch or jewelry box.
- Clean with a soft dry cloth after wearing.
Sterling Silver
- Silver naturally tarnishes over time — this is normal.
- Polish with a silver cloth to restore shine.
- Store in an airtight bag or box to slow tarnishing.
- Avoid exposure to chlorine, saltwater, and sulfur.
Plated Pieces
Plating (such as gold or rhodium plating) is a thin surface layer and wears gradually with use. Keep plated pieces away from water, perfume and friction, and check each product page for its specific care notes.
General Tips
- Put jewelry on last — after makeup, hairspray, and perfume.
- Remove before sleeping to prevent bending or breakage.
- Store pieces separately to avoid scratching.
