Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of an oval diamond catching light with every subtle movement of the hand. This semi-set halo ring frame, crafted in 18K white gold, is designed to cradle a 6 x 4 mm oval center stone, known for its elongated silhouette that visually lengthens the finger with quiet elegance.

The halo setting enhances brilliance while maintaining a low profile, ensuring the ring sits comfortably beneath gloves or daily wear. Expertly finished in Williamsburg, the band features a smooth comfort fit and precise prong work that balances security with refined minimalism.

Each piece is crafted with lab-grown diamonds, reflecting a commitment to ethical sourcing and sustainability without compromising on clarity or fire.

Its slender band and modest height make this mounting ideal for those seeking a ring that integrates seamlessly with stackable bands or stands alone with subtle sophistication.
