Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in 14K yellow gold frames a 7 x 3.5 mm marquise stone with a modern-minimalist structure, designed to amplify the diamond’s clarity and confident geometry.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the halo mount adds subtle brilliance without overwhelming the stone’s architectural elegance. Each piece is meticulously inspected to meet exacting standards of polish and symmetry.

Our commitment to sustainability is reflected in the lab-grown diamond clarity, offering an ethical alternative with reduced environmental impact.

The slender band suits those who appreciate refined detail and a ring that layers well with other bands or stands alone with quiet strength. Its shape elongates the finger, ideal for hands seeking a sleek, contemporary statement.

Resizing is available to ensure the perfect fit, with a typical lead time that respects the care invested in every custom design.
