Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a 12 x 6 mm marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This three-stone semi-set ring offers a foundation crafted from warm 14K rose gold, chosen for its gentle glow and subtle contrast to the cool white gold accents that frame the setting.

Each band is meticulously shaped and hand-finished in our Williamsburg studio, ensuring a smooth comfort fit that wears effortlessly day to day. The low-profile mounting balances presence with practicality, allowing the ring to nestle close to the hand without catching on fabric or gloves.

Our commitment to sustainability is reflected in the lab-grown marquise diamond, offering clarity and brilliance with a significantly reduced environmental footprint. This ethical choice aligns with a modern approach to fine jewelry, where beauty and responsibility coexist.

Designed for those who appreciate architectural elegance and a refined silhouette, this ring complements slender fingers and pairs seamlessly with stackable bands or a wedding band of your choosing. The semi-set style invites you to select a center stone that resonates personally, making the design uniquely yours.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with the same care as the original design. Typical lead times reflect our artisanal process, allowing space for thoughtful customization.
