Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch across the hand. This semi-set three-stone ring foundation in warm 10K rose gold invites your choice of a 7 x 5 mm center stone, framed by two delicate side settings that balance modern minimalism with architectural clarity.

Crafted in Williamsburg, the band’s subtle warmth complements the oval’s graceful silhouette, while the low-profile mounting ensures everyday comfort and ease beneath gloves or stacked alongside other bands. Each curve is polished to a soft sheen, reflecting the studio’s commitment to refined, wearable design.

Our lab-grown diamonds offer a transparent origin story, marrying sustainability with the unmistakable brilliance of precision-cut gems. This ring’s structure is designed for those who appreciate confident simplicity and a clean, contemporary aesthetic.

Ideal for hands that favor elongated shapes, the oval’s gentle taper visually lengthens fingers, while the three-stone layout adds quiet dimension without excess. The semi-set format allows you to select a center diamond that resonates personally, making the ring uniquely yours.

Should resizing be needed, our Brooklyn studio handles adjustments with care to maintain the band’s integrity and finish. Typical lead times reflect the custom nature of your design journey.
