Lab-Grown Diamond Engagement Ring

Imagine the moment light catches the elongated facets of a marquise diamond, casting a delicate, tapered glow that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring foundation in 10K white gold awaits your choice of a 12 x 6 mm marquise center, designed to frame the stone with a circle of smaller diamonds that amplify its sculptural brilliance.

Crafted in our Williamsburg studio, the band is meticulously shaped for a low-profile fit that rests comfortably against the finger, ideal for daily wear without catching or discomfort. The artisan finish reveals subtle hand-polished edges and secure prong settings, ensuring durability alongside refined beauty.

Each lab-grown diamond offers a clarity and sparkle that honors sustainable sourcing, reflecting a commitment to ethical jewelry without compromise.

This design suits those who appreciate a statement piece that remains wearable—its halo setting enhances the marquise’s dramatic silhouette while the white gold band complements a variety of skin tones and personal styles. Its modest height makes it glove-friendly and stackable with other bands.

Should you need resizing, our in-studio experts provide precise adjustments to ensure a perfect fit, with typical lead times tailored to your custom design process.
