Lumière Graduée Necklace

Some pieces don’t just shine.
They flow.

The Lumière Graduée Necklace is designed to follow the natural rhythm of light, a seamless progression of brilliance, where each diamond builds upon the next. A refined expression of balance, proportion, and quiet luxury.

Crafted in solid 14K yellow gold, this necklace features a carefully arranged sequence of lab-grown diamonds, graduating in size toward the center. The result is a soft, luminous curve that sits effortlessly along the neckline, elegant, fluid, and endlessly wearable.

Each diamond is selected for its clarity and fire, offering a brilliance that feels both modern and timeless. The graduated design enhances the natural movement of light, creating a subtle yet captivating presence with every step.

Designed in collaboration with expert jewelers, this piece reflects precision, intention, and a deep understanding of form.

Made to be worn daily.
Made to stay with you.

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.
