Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle sparkle that traces the curve of your hand. This semi-set engagement ring in 18K rose gold offers a delicate frame for a 6 x 3 mm marquise center, its tapered points lending a refined elegance without overwhelming the finger.

Crafted with a low-profile setting, the band sits close to the skin, ensuring comfort throughout daily wear. The rose gold’s warm glow complements the diamond’s crisp facets, while the accent stones add a whisper of brilliance along the shank. Each ring is meticulously finished and inspected in our Williamsburg studio, balancing durability with graceful lines.

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

Designed for those who appreciate subtle sophistication, this ring fits comfortably under gloves and pairs effortlessly with stacking bands. Its slender proportions suit a variety of hand shapes, especially elongating shorter fingers with the marquise’s architectural form.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks.
