Lab-Grown Diamond Engagement Ring

Imagine the elongated silhouette of a marquise diamond catching the light as it gracefully extends along the finger, its tapered points lending a subtle drama to every gesture. This three-stone semi-set ring features a 7 x 3.5 mm marquise center, poised to be paired with your choice of side stones, all cradled in 18K white gold that balances cool refinement with enduring strength.

Each band is meticulously crafted in our Williamsburg studio, where the artisan’s hand ensures a low-profile setting that sits comfortably for daily wear. The smooth finish and gentle curve of the shank offer a natural fit, while the semi-set design invites a personalized touch to complete the composition.

Our commitment to ethical jewelry is reflected in the lab-grown diamonds we champion—offering clarity and brilliance with a lighter environmental footprint.

Ideal for those who appreciate architectural elegance with a modern edge, this ring’s slender shape complements slender to medium finger sizes and layers beautifully with other bands. Its low profile and secure prongs make it glove-friendly and practical for everyday life.

Should you need adjustments, resizing is handled expertly in-house to maintain the integrity of the design.
