Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc that feels both intimate and expansive. This semi-set halo ring foundation in 14K white gold frames the center stone with delicate pavé, designed to amplify brilliance without overwhelming the finger.

Crafted in Williamsburg, the band’s smooth comfort fit and modest profile ensure it slips easily beneath gloves or stacks effortlessly with a wedding band. Each prong is hand-finished to cradle a 6 x 3 mm marquise stone securely, balancing elegance with everyday wearability.

Our commitment to lab-grown diamonds means this ring begins with a gem of exceptional clarity and ethical provenance, reflecting a modern approach to sustainability without compromise.

Ideal for those who appreciate refined geometry and a subtle halo that enhances the marquise’s dramatic shape, this mounting invites a personal center stone choice to complete its story.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers a thoughtful, pressure-free consultation tailored to your rhythm and style.
