Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This semi-set halo engagement ring in 14K rose gold frames a 9 x 4.5 mm marquise stone, known for its elegant taper and ability to visually lengthen the hand.

Crafted in Williamsburg, the band is thoughtfully designed with a low-profile setting that keeps the diamond secure yet unobtrusive, ideal for everyday wear. The rose gold finish is polished to a soft glow, complementing the halo’s delicate pavé accents that enhance brilliance without bulk. Comfort fit shaping ensures the ring sits naturally, whether worn solo or stacked.

Each diamond is lab-grown, offering clarity and sparkle with a smaller environmental footprint. This ethical choice aligns with a modern approach to fine jewelry, marrying beauty with responsibility.

Its slender silhouette suits those who appreciate refined geometry and a ring that transitions seamlessly from daily life to special moments. The halo setting adds visual weight without sacrificing wearability, making it glove-friendly and easy to pair with wedding bands.
