Lab-Grown Diamond Engagement Ring

Imagine the elongated silhouette of a marquise diamond catching morning light, its pointed ends drawing the eye along the finger with subtle drama. This semi-set engagement ring in 14K yellow gold offers a refined foundation for a 10 x 5 mm marquise center stone, framed by delicate accent details that enhance its architectural grace.

Crafted with a low-profile setting, the band sits close to the finger, ensuring comfort for daily wear without sacrificing presence. The warm glow of yellow gold complements the stone’s shape, while precise finishing and inspection guarantee a smooth, durable surface that resists snagging.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Designed for those who appreciate a sleek, elongating form, this ring suits slender to medium finger sizes and pairs effortlessly with stackable bands or wedding rings. Its modest height makes it glove-friendly and ideal for an active lifestyle.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without altering the ring’s integrity.
