Serment Éternel 14K Yellow Gold Lab-Grown Baguette Diamond Anniversary Band – 2 1/4 CTW

Some promises deserve more than a delicate line of diamonds.

The Serment Éternel is a 14K yellow gold lab-grown baguette diamond anniversary band designed with unmistakable presence. A precise row of straight baguette diamonds creates a clean, architectural line across the finger, bringing together the warmth of polished yellow gold and the controlled brilliance of an elongated step cut.

The diamonds total an impressive 2 1/4 carats and are selected in G-H color and VS2 clarity. Each 5 × 2.5 mm baguette is secured with claw prongs that preserve the ring’s refined geometry while allowing the diamonds to remain the focus.

Unlike a traditional round brilliant diamond band, the straight baguette arrangement reflects light in broader, mirror-like flashes. The result feels modern and composed rather than overly ornate, making this ring equally striking as an anniversary band, contemporary wedding band or standalone statement diamond ring.

With a substantial 5.2 mm top width and a smooth comfort-fit interior, Serment Éternel was created to mark the moments that are meant to last.

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.
