Lab-Grown Diamond Engagement Ring

Imagine the quiet thrill of a heart-shaped diamond poised to catch the light with every subtle movement. This semi-set halo engagement ring foundation in 18K white gold is crafted to embrace a 10 x 10 mm center stone, its iconic silhouette offering a tender yet striking statement.

The band’s low-profile setting ensures the ring sits close to the finger, balancing presence with everyday comfort. Expertly finished in Williamsburg, the smooth shank and secure halo mount are designed for durability and ease, making it a reliable companion for daily wear.

Each piece is made to order with a lab-grown diamond, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Its shape and size suit those who appreciate a romantic form with architectural precision, while the halo setting enhances sparkle without adding bulk—ideal for stacking or wearing solo with gloves or bare hands.
