Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a subtle arrow across the finger. This semi-set halo engagement ring in 14K yellow gold frames a 12 x 6 mm marquise stone, offering a refined balance between presence and wearability.

Crafted with a low-profile halo setting, the band sits close to the finger, minimizing snagging while maximizing daily comfort. The smooth 14K yellow gold shank is polished to a soft glow, designed for effortless stacking or solo elegance. Each detail is finished by hand in our Williamsburg studio, ensuring precise prong placement and a secure yet delicate embrace of your chosen center stone.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable practices, reflecting a modern approach to ethical jewelry.

The marquise shape, with its tapered points and elongated form, visually lengthens the finger, making it an excellent choice for those seeking a distinctive yet graceful profile. Its halo setting enhances sparkle without adding bulk, ideal for everyday wear and glove-friendly occasions.

Should you need resizing, our in-studio experts provide careful adjustments to maintain the ring’s integrity and comfort.
