Lab-Grown Diamond Engagement Ring

Sunlight catches the halo’s delicate circle, scattering light around the 5.2 mm round center stone’s brilliant fire. This semi-set engagement ring offers a refined foundation in 10K yellow gold, designed to cradle your chosen lab-grown diamond with precision.

Crafted with a low-profile halo setting, the band sits close to the finger, reducing snagging and enhancing comfort for everyday wear. The smooth finish and subtle taper ensure the ring feels balanced and secure, while the halo’s micro-pavé detail adds a whisper of sparkle without overwhelming the center stone.

Each piece is hand-finished in our Williamsburg studio, where expert jewelers inspect every facet and prong to meet exacting standards. The ethical clarity of lab-grown diamonds complements the sustainable ethos behind this ring’s creation.

Its modest height and streamlined silhouette make it ideal for those seeking a ring that layers effortlessly with wedding bands or stackable rings. The warm glow of 10K yellow gold enhances the round diamond’s classic brilliance, flattering a variety of hand shapes and sizes.

Should you need resizing or prefer a custom stone, our team is happy to assist with personalized adjustments and guidance.
