Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that seems to stretch beyond the fingertips. This three-stone semi-set engagement ring invites you to choose a center stone that will become the heart of its graceful arc.

Crafted from warm 10K yellow gold, the band curves gently to cradle side stones that enhance the marquise’s tapered drama. The low-profile setting ensures the ring sits comfortably for daily wear, while the polished finish reflects the Brooklyn studio’s meticulous handwork. Each piece is inspected for balance and durability, designed to move seamlessly from morning light to evening glow.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful approach to sustainability and ethical sourcing.

The slender band and modest height make this ring ideal for those who appreciate subtle elegance and a fit that complements slender fingers or pairs effortlessly with a wedding band. Its three-stone design symbolizes past, present, and future, perfect for a story told in light and form.

Should you wish to adjust the fit, resizing is available to ensure comfort without compromising the ring’s refined silhouette.
