Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with a graceful sweep. This semi-set three-stone ring invites you to select a 10 x 5 mm marquise center, framed by two smaller stones that balance drama with quiet elegance.

Crafted from warm 14K yellow gold, the band is shaped with a subtle comfort fit, its smooth interior and gently tapered shoulders designed for daily wear. The setting’s low profile keeps the stones close to the hand, reducing snagging while allowing light to flood the facets from every angle. Each prong is hand-finished in our Williamsburg studio, ensuring secure hold and refined detail.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both the earth and your values. This ring’s ethical foundation complements its artisan construction, marrying sustainability with timeless design.

Ideal for those who appreciate a statement piece that remains wearable—its slender band layers effortlessly with other rings or stands alone with quiet confidence. The marquise shape’s elongating effect flatters a variety of hand sizes, while the three-stone layout adds narrative depth to your engagement story.

Should you need resizing or wish to discuss stone options, our Brooklyn studio welcomes your questions with thoughtful guidance and no pressure. Typical lead times vary depending on customization.
