Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set halo ring foundation in 10K yellow gold offers a warm, inviting glow that complements the stone’s dramatic shape.

Crafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that sits close to the finger, ideal for daily wear. The halo setting, designed to surround the center stone with delicate pavé diamonds, enhances brilliance while maintaining a low profile that slips easily beneath gloves or sleeves. Each piece is hand-finished and inspected to ensure smooth edges and a refined polish.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond center, offering clarity and sparkle with a significantly reduced environmental footprint.

This ring suits those who appreciate bold geometry paired with artisan detail—its slender 9 x 4.5 mm marquise shape elongates the finger, while the halo adds a subtle vintage-inspired frame. The semi-set nature invites you to select a center stone that reflects your personal story.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive, pressure-free consultations to tailor fit and finish.
