Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This three-stone semi-set ring invites your choice of a 12 x 6 mm center stone, framed by two smaller companions that enhance its graceful drama without overwhelming.

Crafted in 10K white gold, the band offers a subtle gleam with a comfort fit that settles smoothly beneath the finger. The setting’s low profile ensures everyday wearability, while precise hand finishing in our Williamsburg studio reveals the quiet strength of expert craftsmanship.

Each diamond is lab-grown, reflecting a commitment to ethical jewelry that honors both clarity and conscience. The marquise shape’s tapered form visually elongates the finger, making it a refined choice for those who appreciate architectural elegance with a romantic edge.

This ring suits hands that favor slender, sculptural lines and pairs beautifully with stackable bands or a delicate wedding band. Its semi-set design allows you to select a center stone that resonates personally, ensuring a truly custom expression.

Resizing is handled with care in-studio, maintaining the integrity of the setting and finish. Typical lead times reflect our dedication to thoughtful, handcrafted work rather than rushed production.
