Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a graceful, tapered brilliance. This semi-set halo engagement ring invites you to select a 9 x 4.5 mm center stone, ready to be embraced by a delicate frame of pavé diamonds that amplify its fiery sparkle.

Crafted from 18K white gold in our Williamsburg studio, the band is meticulously hand-finished to a smooth comfort fit, designed for everyday wear without sacrificing elegance. The low-profile halo setting balances presence with practicality, allowing the ring to nestle comfortably alongside other bands or stand alone with quiet confidence.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer exceptional clarity and brilliance with a smaller environmental footprint.

Ideal for those who appreciate architectural form and refined craftsmanship, this ring complements slender fingers and suits a modern aesthetic while remaining versatile enough for stacking or solo wear. Its semi-set nature means you can personalize the center stone to your exact preference, ensuring a truly unique expression.

Should you need resizing or advice on care, our Brooklyn studio provides attentive support to ensure your ring fits perfectly and retains its brilliance over time.
