Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender, dramatic silhouette that dances with every movement. This solitaire engagement ring, set in cool platinum, frames the 10 x 5 mm stone with a delicate yet secure four-prong setting, crafted to showcase the gem’s tapered brilliance without distraction.

Hand-forged in our Williamsburg studio, the band is polished to a satiny finish that feels weightless and smooth against the skin. Its low-profile design ensures the ring sits comfortably beneath gloves or alongside other stackable bands, making it a versatile choice for daily wear.

Each lab-grown diamond is selected for clarity and ethical provenance, reflecting a commitment to sustainability without compromising on luminous fire. The marquise cut’s distinctive shape elongates the finger, lending an elegant, architectural grace to those who appreciate refined geometry.

Resizing is available to ensure a precise fit, with careful attention to maintaining the ring’s structural integrity and balance. Typical lead times for custom adjustments are communicated transparently during your consultation.
