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 in 18K rose gold frames a 7 x 3.5 mm marquise center, ready to be paired with a lab-grown diamond of your choosing.

The halo setting is crafted to sit low against the hand, offering a sleek profile that balances presence with everyday comfort. The rose gold band is polished to a soft glow, its subtle warmth complementing the diamond’s sharp geometry without overwhelming it. Each curve and prong is meticulously finished in our Williamsburg studio, ensuring durability and ease of wear.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or brilliance.

Designed for those who appreciate refined details and a ring that fits seamlessly into daily life, this halo mounting pairs well with slender bands and suits fingers that favor elongated shapes. Its low profile makes it glove-friendly and stackable, ideal for layering or solo wear.

Should you need resizing, our in-house artisans handle adjustments with care to maintain the ring’s structural integrity. Typical lead times for setting your chosen stone are communicated clearly during consultation.
