Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise shape, casting a slender, elegant silhouette that draws the eye along the hand’s natural lines. This semi-set halo engagement ring features an 8 x 4 mm marquise center, designed to balance presence with subtlety.

Crafted in 10K yellow gold, the band offers a warm glow that complements the diamond’s crisp facets. The halo setting enhances brilliance while maintaining a low profile, ensuring the ring sits comfortably beneath gloves or daily wear. Each piece is meticulously finished and inspected in our Williamsburg studio, emphasizing durability and refined detail.

Our lab-grown diamonds provide a clear, sustainable alternative without compromising on sparkle or integrity.

The ring’s slender band and secure setting suit those seeking a refined yet practical engagement ring—ideal for stacking or solo wear. Its low profile and comfort fit make it a natural choice for everyday life.

Should you need resizing, we handle adjustments with care to preserve the ring’s proportions and finish.
