Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle, tapered sparkle that draws the eye along the finger’s natural line. This solitaire semi-set ring in 14K yellow gold offers a refined foundation for a 9 x 4.5 mm marquise center stone, emphasizing sleek geometry without excess height.

Crafted with a low-profile setting, the band’s gentle curve and secure prongs ensure daily comfort and resilience, ideal for hands that move through life without pause. Each piece is meticulously finished in our Williamsburg studio, where precision meets understated elegance in every detail.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable practices, reducing environmental impact without compromising beauty.

Designed for those who appreciate a balance of statement and subtlety, the marquise shape elongates the finger gracefully, while the solitaire setting keeps the focus clear and confident. Its modest profile fits comfortably beneath gloves and stacks effortlessly with complementary bands.

Should you wish to adjust sizing, our Brooklyn studio offers expert resizing to maintain the ring’s integrity and fit.
