Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set halo ring foundation in 18K yellow gold awaits your choice of a 10 x 5 mm center stone, designed to cradle the gem with delicate artisan precision.

Hand-forged in our Williamsburg studio, the band’s warm gold gleams with a soft satin finish, while the halo setting promises a subtle frame that enhances brilliance without overpowering. The low-profile design ensures everyday comfort, slipping easily beneath gloves or alongside stackable bands.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and sparkle with a smaller environmental footprint. The marquise shape’s graceful elongation flatters a range of hand sizes, lending an elegant, vintage-inspired edge to modern wear.

Should you need resizing, our in-house jewelers provide careful adjustments to ensure a perfect fit without compromising the setting’s integrity. Typical lead times accommodate thoughtful customization, honoring the bespoke nature of your ring.
