Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a sleek, confident line. This three-stone semi-set ring in 18K white gold frames an 8 x 4 mm marquise center, offering a modern-minimalist statement that balances architectural clarity with subtle grace.

Crafted in Williamsburg, the band’s low-profile setting ensures the ring sits comfortably for daily wear, while the clean lines of the three-stone arrangement emphasize structure without excess. Each piece is meticulously finished by hand, polished to a soft sheen that complements the diamond’s sharp facets.

Our lab-grown diamonds provide the same brilliance and clarity as mined stones, with a significantly reduced environmental footprint—an ethical choice woven into every detail.

The slender white gold band suits those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable rings. Its comfort fit and modest height make it glove-friendly and ideal for an active lifestyle.

Should you wish to adjust sizing, our in-studio experts in Williamsburg handle custom fits with care and precision, ensuring your ring feels as natural as it looks.
