Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a subtle, elegant shadow along the finger. This semi-set solitaire invites you to select a center stone that balances dramatic presence with refined geometry.

Crafted in warm 14K yellow gold, the mounting features a low-profile setting designed for everyday wear. The slender prongs secure the stone while maintaining a sleek silhouette that slips comfortably beneath gloves or rings stacked alongside it. Each band is hand-finished in our Williamsburg studio, ensuring smooth edges and a comfort fit tailored to daily life.

Our commitment to lab-grown diamonds means your chosen marquise will shine with clarity and conscience, reflecting a sustainable approach without compromise.

This ring suits those who appreciate architectural elegance paired with practical design—ideal for hands that favor elongated shapes and a setting that stays close to the skin.

Resizing is straightforward, handled with care in-studio to preserve the integrity of the band and setting.
