Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident, architectural edge. This semi-set engagement ring foundation in warm 10K yellow gold frames a 12 x 6 mm center stone with delicate accent settings, designed to enhance clarity and structure without distraction.

Crafted in Williamsburg, Brooklyn, the band is shaped for comfort and everyday wear, its smooth finish and low profile ensuring it slips easily beneath gloves or stacks seamlessly with other rings. Each piece is meticulously hand-finished and inspected to meet exacting standards of balance and polish.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering brilliance and clarity with a smaller environmental footprint. This mounting invites your choice of a marquise stone, celebrated for its tapered points and graceful elongation that flatters the hand.

Resizing is straightforward, handled in-studio with care to preserve the ring’s clean lines. Whether you visit us in Williamsburg or design remotely, this semi-set ring offers a modern-minimal foundation for a truly personal engagement.
