Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to stretch across the hand like a whispered promise. This three-stone semi-set engagement ring in 18K yellow gold frames a 6 x 3 mm marquise center, its pointed ends drawing the eye along a graceful arc.

Each element is meticulously crafted in our Williamsburg studio, where the warm glow of yellow gold is hand-finished to a soft, satiny sheen. The setting’s low profile ensures the ring sits close to the finger, offering comfort for everyday wear while the side stones balance the center’s dramatic shape with subtle brilliance.

Our lab-grown diamonds bring clarity and sparkle without compromise, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

Designed for those who appreciate romantic detail and refined geometry, this ring complements slender fingers and pairs effortlessly with stacking bands or a wedding band of your choice. Its gentle curve and secure setting make it glove-friendly and ideal for daily life.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
