Lab-Grown Diamond Engagement Ring

Imagine the elongated silhouette of an 8 x 4 mm marquise diamond catching light with a subtle, tapered brilliance—its halo setting amplifies this effect while maintaining a sleek profile. Crafted in 14K white gold, this semi-set ring offers a refined foundation ready to showcase your chosen center stone, framed by delicate pavé that enhances sparkle without bulk.

The band’s low-profile design ensures comfort for everyday wear, slipping easily beneath gloves or alongside other stackable pieces. Expertly finished in Williamsburg, Brooklyn, each curve and prong is inspected for precision and durability, reflecting a commitment to craftsmanship that balances technical assurance with understated elegance.

Our lab-grown diamonds provide a clear ethical advantage, offering the same optical beauty and structural integrity as mined stones with a smaller environmental footprint.

This ring suits those who appreciate architectural grace paired with practical wearability—its narrow shape elongates the finger while the halo adds dimension without height. The semi-set format invites personal choice, allowing you to select a marquise diamond that resonates with your vision.

Resizing is straightforward, handled in-studio to maintain the ring’s structural integrity and finish.
