Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo engagement ring in 18K yellow gold frames a 6 x 3 mm marquise center with delicate pavé, enhancing its tapered drama without adding bulk.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease beneath gloves or sleeves. The warm glow of yellow gold is polished to a satin finish on the shank, balancing subtlety with refined shine. Each piece undergoes meticulous inspection in our Williamsburg studio to ensure precision and durability.

Our lab-grown diamonds offer the same optical brilliance as mined stones, with a lighter environmental footprint and traceable origins.

This ring suits those who appreciate architectural elegance paired with practical wearability—its slender silhouette complements narrow fingers and layers seamlessly with other bands. The halo setting adds visual width without overwhelming smaller hands.

Resizing is available to ensure a perfect fit, with typical lead times of 4–6 weeks from design approval.
