Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the length of the finger. This semi-set halo engagement ring in 18K yellow gold offers a refined foundation for a 12 x 6 mm center stone, designed to amplify brilliance while maintaining a low profile.

Crafted with precision, the band’s smooth finish and subtle halo setting provide both security and comfort, making it suitable for everyday wear. The low-profile design ensures it slips easily under gloves or sleeves without catching, while the sturdy yellow gold frame balances elegance with durability.

Each piece is thoughtfully created in our Williamsburg studio using lab-grown diamonds, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire.

The elongated marquise shape naturally elongates the finger, flattering a variety of hand sizes and lending a distinctive, graceful presence. Its semi-set state invites you to select a center stone that resonates personally, allowing for a truly bespoke expression.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care recommendations to preserve the ring’s luster over time.
