Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a subtle drama that draws the eye along the finger’s natural line. This semi-set halo engagement ring in 18K rose gold offers a delicate frame for a 6 x 3.5 mm marquise center, enhancing its graceful taper without overwhelming the stone’s refined shape.

Crafted with a low-profile halo setting, the ring balances presence and practicality—its secure prongs and smooth band ensure comfort for daily wear while maintaining a confident architectural edge. The warm blush of rose gold complements the diamond’s brilliance, polished to a satin finish that resists scratches and softens the overall feel.

Each piece is meticulously inspected in our Williamsburg studio, where expert jewelers refine every detail to meet exacting standards. The lab-grown diamond at its heart reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and sparkle without compromise.

Designed for those who appreciate subtle sophistication, this ring suits slender to medium finger sizes and pairs effortlessly with stackable bands or wedding rings. Its low profile fits comfortably under gloves or sleeves, making it a versatile choice for everyday life.

Should you need a custom fit, resizing is straightforward and handled with care in-house, ensuring your ring remains as comfortable as it is captivating.
