Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a 10 x 5 mm marquise diamond catches the light with its signature tapered drama. This semi-set solitaire ring, crafted in warm 14K yellow gold, offers a refined foundation ready to showcase your chosen center stone.

The band’s low-profile design ensures the setting sits close to the finger, minimizing snagging while maintaining a confident presence. Expertly finished in Williamsburg, the smooth shank balances durability with comfort, ideal for everyday wear.

Each lab-grown diamond option reflects a commitment to ethical sourcing and sustainability, marrying brilliance with conscience.

Its slender silhouette suits those who appreciate a sleek, modern aesthetic and prefer a ring that layers effortlessly with wedding bands or stackable styles. The semi-set format invites personalization, allowing you to select a marquise diamond that resonates with your vision.

Should you need resizing, our Brooklyn studio handles adjustments with precision to maintain the ring’s integrity and comfort fit.
