Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a subtle, tapered sparkle that draws the eye along the finger’s natural line. This semi-set halo engagement ring in 18K white gold offers a refined low-profile design, crafted to sit comfortably beneath daily gloves and sleeves.

The halo setting surrounds the 8 x 4 mm marquise center with a delicate frame of pavé stones, enhancing brilliance without adding bulk. Each element is hand-finished in our Williamsburg studio, ensuring a smooth comfort fit and precise prong work that secures the stone while maintaining a sleek profile.

Our commitment to lab-grown diamonds means this ring carries a clarity and ethical transparency that aligns with sustainable values, crafted with minimal environmental impact.

Designed for those who appreciate subtle drama and everyday elegance, the narrow band complements slender to medium finger sizes and layers effortlessly with wedding bands or stackable rings.

Should you need a custom adjustment, resizing is handled expertly in-house to preserve the ring’s integrity and finish.
