Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo engagement ring in 10K yellow gold frames a 7 x 3.5 mm marquise center with a delicate circle of pavé stones, enhancing its signature tapered drama without adding bulk.

Crafted for everyday wear, the low-profile setting keeps the diamond close to the finger, minimizing snagging while preserving brilliance. The warm yellow gold band is polished to a smooth finish, offering a comfortable fit that slides easily beneath gloves or alongside other stackable rings.

Each ring is thoughtfully designed and finished in our Williamsburg studio, where precision meets quiet durability. The semi-set design invites you to select a lab-grown diamond of exceptional clarity and ethical origin, reflecting a commitment to sustainability without compromise.

Ideal for those who appreciate architectural elegance paired with practical comfort, this halo setting balances visual impact with subtlety. Its slender silhouette complements narrow fingers and suits a variety of personal styles, from minimalist to vintage-inspired.
