Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it creates a subtle play of light that draws the eye along the finger’s natural line. This semi-set engagement ring frame in 18K white gold offers a secure, low-profile foundation designed to showcase a 6 x 3.5 mm marquise center stone with delicate accent details that enhance its refined geometry.

Crafted with precision in Williamsburg, the band’s smooth finish and modest height ensure comfortable daily wear without catching or shifting. The setting’s engineering balances protection with visibility, allowing the diamond’s signature pointed ends to shine while maintaining a sleek profile beneath gloves or sleeves.

Each ring is thoughtfully made using lab-grown diamonds, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Ideal for those who appreciate architectural elegance paired with practical design, this mounting suits slender to medium finger sizes and pairs effortlessly with stackable bands or wedding rings of varying widths.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit with minimal turnaround.
