Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of the marquise diamond, casting a slender, luminous shadow that dances with every movement. This 9 by 4.5 mm center stone is embraced by a delicate halo of pavé-set lab-grown diamonds, amplifying its tapered drama with a subtle glow.

Crafted in 14K white gold, the ring’s low-profile setting balances refined elegance with everyday wearability. The artisan’s hand polishes each facet and prong to a satin-smooth finish, ensuring the band feels weightless and comfortable against the skin. The halo setting is meticulously secured to highlight the marquise’s signature pointed ends while protecting them from daily knocks.

Our lab-grown diamonds offer a clarity and brilliance indistinguishable from mined stones, with a fraction of the environmental impact—an ethical choice made without compromise.

Designed for those who appreciate sculptural geometry and subtle sparkle, this ring suits slender to medium finger sizes and layers effortlessly with stackable bands or wedding rings. Its modest height slips easily beneath gloves or sleeves, making it a practical companion for daily life.

Should you need a custom fit, resizing is handled in-studio with care to preserve the integrity of the halo and setting.
