Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond stretches gracefully across the finger, catching light with a subtle, tapered brilliance that feels both bold and refined.

This semi-set solitaire ring is crafted in 14K yellow gold, offering a warm glow that complements the stone’s sharp geometry. Designed with a low-profile setting, the mounting sits close to the skin, ensuring comfort for everyday wear without sacrificing presence. Each piece is meticulously finished in our Williamsburg studio, where precise hand polishing and secure prong work guarantee durability and ease of maintenance.

Our commitment to lab-grown diamonds means this marquise center is ethically sourced, with clarity and sparkle that rival mined stones while reducing environmental impact.

The slender band and modest height make this ring ideal for those who appreciate a sleek silhouette that layers effortlessly with other bands or stands confidently alone. Its 8 x 4 mm size balances visibility with subtlety, flattering a range of hand shapes and sizes.

Should you need adjustments, resizing is handled expertly in-house to maintain the ring’s structural integrity and finish.
