Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across the skin. This semi-set halo engagement ring, crafted in warm 18K yellow gold, frames a 7 x 3.5 mm marquise center with delicate pavé accents that amplify its graceful sparkle.

Each curve of the band is hand-finished in our Williamsburg studio, polished to a soft glow that feels smooth against the finger. The low-profile setting ensures everyday comfort and ease beneath gloves or alongside stackable bands, making it a subtle companion for daily wear.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both beauty and sustainability without compromise.

Designed for those who appreciate refined romance and architectural elegance, this ring complements slender fingers and elongates the hand’s natural lines. Its halo setting adds a whisper of vintage charm while maintaining a modern silhouette.

Should you wish to adjust sizing, our Brooklyn studio provides expert resizing with care to preserve the ring’s delicate balance.
