Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate path of light. This semi-set halo ring in warm 14K rose gold invites you to choose a center stone that balances bold geometry with graceful elongation.

Crafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that rests naturally against the finger. The halo setting, meticulously hand-set with pavé diamonds, enhances the marquise’s signature sparkle while maintaining a low profile that slips easily under gloves or sleeves. Each piece undergoes careful finishing and inspection to ensure a smooth, polished surface and secure mounting.

Our diamonds are lab-grown, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate architectural elegance paired with artisanal detail—its slender band and halo frame complement slender to medium finger sizes, perfect for stacking or wearing solo.

Should you need resizing, our in-house jewelers provide precise adjustments to maintain the ring’s balance and comfort. Lead times vary slightly depending on stone selection, but we guide you through every step with care.
