Lumière Diamond Bypass Ring

There is something undeniably captivating about a piece that refuses symmetry, yet achieves perfect balance. The Éclipse Diamond Bypass Ring is designed around this idea, two fluid lines of brilliance that move past one another, creating a quiet tension between structure and motion.

Crafted in solid 14K gold, available in both luminous yellow gold and refined white gold, the ring wraps elegantly around the finger with a natural, almost effortless flow. Its silhouette feels alive, never static, catching light from every angle as if in constant movement.

A carefully graduated composition of lab-grown diamonds enhances this effect. Each stone is placed with intention, increasing in presence as the design unfolds, leading the eye toward the center where brilliance feels most intense. The result is not excess, but control, a restrained expression of luxury where every detail serves the whole.

Polished to a mirror-like finish, the gold reflects light with quiet confidence, while the diamonds bring a precise, refined fire. Together, they create a piece that feels both contemporary and enduring, bold in design, yet timeless in presence.

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.
