Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender, luminous shadow that dances with every movement. This semi-set halo ring invites you to choose a 7 x 3.5 mm marquise center stone, its pointed silhouette evoking a quiet drama and graceful elongation across the finger.

Crafted in warm 14K yellow gold, the band is polished to a gentle sheen that complements the halo’s delicate frame. The low-profile setting balances presence with practicality, designed to sit comfortably beneath gloves or alongside other stackable bands. Each piece is meticulously finished in our Williamsburg studio, where hand inspection ensures smooth edges and a refined comfort fit.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful footprint—an ethical choice that honors both beauty and sustainability.

This ring suits those who appreciate subtle statement jewelry that moves effortlessly from daily wear to special moments. The halo setting enhances the marquise’s natural sparkle without overwhelming the hand’s silhouette.

Should you need resizing or prefer a custom stone cut, our Brooklyn studio welcomes your vision with expert guidance and attentive care.
