Lab-Grown Diamond Engagement Ring
When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—an elegant statement of refined confidence. This semi-set engagement ring foundation in 14K white gold offers a sleek, modern-minimal frame designed to highlight a 6 x 3.5 mm marquise center stone of your choosing.
Crafted in Williamsburg, the band’s clean lines and subtle accents balance clarity with structure, while a low-profile setting ensures everyday comfort and ease beneath gloves or alongside stackable bands. Each piece is meticulously finished by hand, polished to a soft sheen, and inspected for precision before it leaves the studio.
Our commitment to lab-grown diamonds means your ring carries a clear ethical edge—sustainably sourced with the same brilliance and durability as mined stones, but with a lighter environmental footprint.
This design suits those who appreciate architectural elegance with a contemporary twist, especially flattering on slender fingers where the marquise shape elongates the hand. The semi-set style invites you to select a center stone that reflects your unique story.
Resizing is straightforward, handled expertly in-studio to maintain the ring’s clean profile and comfort fit.
