Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This semi-set halo ring in 14K yellow gold frames a 7 x 3.5 mm marquise center, inviting you to choose a stone that balances drama with refined elegance.

Crafted in Williamsburg, the band’s warm gold glow is polished to a satin finish that feels smooth against the skin, while the halo setting enhances the diamond’s brilliance without adding bulk. The low-profile design ensures everyday comfort, slipping easily beneath gloves or alongside stackable bands.

Each lab-grown diamond offers clarity and sparkle with a smaller environmental footprint, reflecting a commitment to ethical jewelry without compromise. The marquise shape’s tapered points elongate the finger, ideal for those who appreciate a blend of vintage charm and modern geometry.

Should you need resizing, our Brooklyn studio handles adjustments with care, ensuring the ring fits seamlessly into your daily life. Lead times accommodate thoughtful customization, allowing your vision to unfold naturally.
