Continuity. Precision. Radiance.

The Ligne Éclat Royale necklace is formed in solid 14K white gold, composed of a continuous line of precisely set round diamonds. Each stone is positioned with exact spacing and alignment, creating a seamless flow of light around the neckline.

The structure follows the natural curve of the body, allowing the necklace to sit evenly while maintaining flexibility through its articulated links. The four-prong setting secures each diamond individually, maximizing exposure to light without compromising stability.

The result is controlled brilliance, consistent, refined, and uninterrupted across the entire length.

A lifetime piece.

How to Care for Your Jewelry

With the right care, your Oxfordum pieces will last for years. Follow these simple guidelines to keep your jewelry looking its best.

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.

Stainless Steel (Watches & Accessories)

• Wipe with a damp cloth to remove sweat and oils.
• Safe for daily wear — highly resistant to tarnish and scratching.
• Avoid abrasive cleaners.

Waterproof & Tarnish Resistance

Many of our pieces feature PVD coating or rhodium plating for enhanced durability. Check individual product pages for specific care instructions. As a general rule: remove jewelry before swimming in chlorinated pools or saltwater.

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.
