Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This three-stone semi-set ring in 10K white gold offers a refined foundation for a 12 x 6 mm marquise center, designed with a low-profile setting that balances presence with everyday comfort.

Crafted in Williamsburg, Brooklyn, the band’s subtle curve and secure prong work ensure the stones sit close to the hand, minimizing snagging while maintaining a confident architectural form. The cool white gold finish is polished to a soft sheen, complementing the diamond’s crisp facets without overwhelming its shape.

Each lab-grown diamond is selected for clarity and ethical provenance, reflecting a commitment to sustainable fine jewelry without compromise. The semi-set design invites your choice of center stone, allowing for a personalized expression within a thoughtfully engineered mounting.

Ideal for those who appreciate a sculptural yet wearable ring, this style suits slender to medium finger widths and layers gracefully with stackable bands or wedding rings. Its low profile makes it glove-friendly and practical for daily life.

Resizing is available to ensure a precise fit, with typical lead times reflecting careful hand-finishing and quality control.
