Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This three-stone semi-set engagement ring features a 6 x 3 mm marquise center, poised to be paired with your choice of side stones for a personalized narrative.

Handcrafted in 14K yellow gold, the band’s gentle curve and polished finish balance bold geometry with everyday comfort. The low-profile setting ensures the ring sits close to the hand, making it glove-friendly and ideal for daily wear. Each piece is meticulously inspected in our Williamsburg studio, where artisan techniques meet modern precision.

Our diamonds are lab-grown, offering clarity and brilliance with a smaller environmental footprint—an ethical choice that quietly honors your values.

The slender marquise shape elongates the finger, flattering a range of hand sizes, while the three-stone design invites stacking or solo wear. Its comfort fit band adapts seamlessly to active lifestyles without sacrificing elegance.

Should you need resizing or wish to explore side stone options, our Brooklyn studio provides personalized consultations to ensure your ring fits perfectly and reflects your vision.
