Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise shape, casting a slender, graceful silhouette across the hand. This semi-set halo engagement ring foundation in 18K white gold is crafted to embrace an 8 x 4 mm marquise diamond, its low-profile setting designed for everyday ease without sacrificing brilliance.

The band’s polished finish and secure halo setting offer both subtle sparkle and structural integrity, ensuring the ring sits comfortably with a smooth inner surface that contours naturally to the finger. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of craftsmanship and durability.

Our commitment to lab-grown diamonds means this ring supports a more sustainable approach to fine jewelry, reducing environmental impact while maintaining exceptional clarity and fire.

Ideal for those who appreciate architectural elegance paired with practical wearability, this mounting suits slender to medium finger sizes and pairs effortlessly with stackable bands or wedding rings. Its low profile makes it glove-friendly and unobtrusive for daily life.

Should you need resizing or prefer a custom stone setting, our Brooklyn studio offers personalized consultations to tailor your ring precisely.
