Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set three-stone engagement ring features an 8 x 4 mm marquise center, poised to be paired with your choice of lab-grown diamond for a personalized statement.

Crafted from 18K white gold, the band is shaped with a subtle comfort fit and a low-profile setting that balances presence with everyday ease. Each prong is hand-finished in our Williamsburg studio, ensuring secure hold and refined detail without excess height, making it glove-friendly and stackable alongside wedding bands or accent rings.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, offering clarity and brilliance with a significantly reduced environmental footprint.

This design suits those who appreciate architectural elegance with a touch of vintage-inspired drama, ideal for slender to medium finger sizes where the marquise shape elongates and flatters the hand.

Should you need resizing, our in-house artisans adjust the band with precision to maintain the ring’s balance and comfort.
