Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with quiet drama. This semi-set solitaire ring in 10K rose gold offers a delicate foundation, ready to cradle an 8 x 4 mm marquise stone chosen for its graceful, tapered brilliance.

Crafted with a low-profile setting, the band sits close to the hand, minimizing snagging while maximizing comfort for everyday wear. The warm blush of rose gold complements the diamond’s fire, polished to a smooth finish that feels natural against the skin. Each mounting is meticulously inspected in our Williamsburg studio to ensure precision and durability.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or sparkle.

Designed for those who appreciate subtle elegance, this ring’s slender band and streamlined silhouette suit slender to medium finger sizes and stack beautifully with wedding bands or other fine jewelry. Its low profile makes it glove-friendly and ideal for an active lifestyle.

Should you need resizing or prefer a custom setting adjustment, our Brooklyn studio offers personalized consultations to tailor the fit and finish.
