Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a striking, tapered brilliance that draws the eye along the finger’s natural line. This semi-set halo engagement ring foundation in 14K white gold offers a delicate frame designed to amplify that signature sparkle.

Crafted in our Williamsburg studio, the band is hand-finished with a smooth comfort fit, ensuring it sits low and secure for everyday wear. The halo setting, ready to embrace a 9 x 4.5 mm marquise center, is meticulously formed to balance protection with maximum light reflection, enhancing the diamond’s fiery facets.

Each piece begins with responsibly sourced 14K white gold, chosen for its enduring strength and subtle sheen, then undergoes rigorous inspection to meet exacting standards. The semi-set approach invites you to select a lab-grown diamond of exceptional clarity and brilliance, aligning with a commitment to ethical jewelry that respects both people and planet.

This ring suits those who appreciate refined geometry and a statement that feels both modern and personal. Its low-profile design pairs effortlessly with stacking bands or a wedding band, while the comfort fit ensures it remains glove-friendly and unobtrusive through daily moments.
