Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a delicate, tapered sparkle that seems to dance with every movement. This semi-set halo engagement ring foundation in polished platinum offers a refined stage for a 12 x 6 mm marquise center stone, designed to amplify its dramatic brilliance while embracing the finger with a subtle, low-profile presence.

Crafted in Williamsburg, Brooklyn, the platinum band is meticulously finished to a smooth comfort fit, ensuring it sits gracefully for daily wear. The halo setting, ready to frame your chosen marquise, enhances the diamond’s slender shape with a whisper of surrounding light, balancing boldness with elegance. Each piece undergoes careful inspection to meet exacting standards of craftsmanship and durability.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and beauty with a lighter environmental footprint. This ring suits those who appreciate architectural grace paired with a modern sensibility—its streamlined form slips easily beneath gloves and layers seamlessly with other bands.
