Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger. This semi-set halo engagement ring in 10K yellow gold frames a 7 x 3.5 mm marquise stone, ready to cradle your chosen center with precision.

Crafted with a low-profile setting, the halo gently elevates the diamond while maintaining a sleek silhouette that slips comfortably beneath gloves and daily wear. The warm yellow gold band is polished to a satin finish, offering a soft tactile contrast to the crisp geometry of the marquise cut. Each mounting is carefully inspected in our Williamsburg studio to ensure durability and balance for everyday life.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

The ring’s slender band and modest height suit slender to medium finger sizes, ideal for those seeking a refined yet distinctive statement. Its design supports stacking with complementary bands or wearing solo for understated elegance.

Should you need resizing, our in-studio experts handle adjustments with care to preserve the setting’s integrity.
