Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along a sleek, architectural line. This semi-set three-stone ring foundation in 14K white gold offers a modern-minimal framework, designed to showcase an 8 x 4 mm marquise center with clarity and quiet confidence.

Crafted in Williamsburg, the band’s clean edges and low-profile setting ensure a comfortable fit that slips easily beneath gloves or stacks seamlessly with other bands. Each curve is polished to a satin finish, balancing subtle sheen with everyday wearability. The three-stone layout invites personal expression, allowing you to select side stones that complement the center’s dramatic shape.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering brilliance and ethical clarity without compromise. This ring’s refined structure suits hands that appreciate architectural geometry and a statement that’s both modern and enduring.
