Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it whispers a quiet drama—an elegant point that draws the eye along the finger’s natural line. This three-stone semi-set engagement ring in 18K white gold frames a 10 x 5 mm marquise center with two delicate side stones, balancing architectural grace with gentle sparkle.

Crafted in Williamsburg, the band’s smooth comfort fit and low-profile setting ensure it wears seamlessly every day, slipping easily beneath gloves or alongside stackable bands. Each curve is hand-finished for a refined polish that catches light without overwhelming, while the prongs cradle the marquise securely, highlighting its signature tapered points.

Our commitment to sustainability shines through the lab-grown diamond’s clarity and brilliance—ethically sourced with a fraction of the environmental impact of mined stones.

Ideal for those who appreciate a blend of classic form and modern intention, this ring suits slender to medium finger shapes, enhancing length and lending a subtle elongation. The semi-set design invites your choice of center stone, allowing a personal touch to this poetic expression.

Resizing is available to ensure a perfect fit, with careful attention to preserving the ring’s delicate balance.
