Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to stretch beyond the finger’s natural line. This semi-set halo engagement ring in 18K white gold frames a 6 x 3.5 mm marquise center, inviting you to choose the perfect stone to complete its poetic embrace.

Crafted in Williamsburg, the band’s polished finish and low-profile setting ensure a comfortable fit for daily wear, while the halo of smaller stones amplifies the center’s fiery sparkle without overwhelming its refined shape. Each piece is meticulously inspected to meet exacting standards of symmetry and polish, reflecting the quiet precision of Brooklyn’s artisan tradition.

Our commitment to lab-grown diamonds means your ring carries a clarity and ethical provenance that honors both the earth and your values, with a significantly reduced environmental footprint.

Designed for those who appreciate subtle drama and graceful elongation, this ring suits slender fingers and pairs beautifully with stackable bands or a simple wedding band. Its low profile makes it glove-friendly and unobtrusive for everyday life.

Should you need resizing or prefer a custom stone selection, our Brooklyn studio offers a pressure-free experience tailored to your vision and timeline.
