Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set halo ring invites your choice of a 7 x 3.5 mm lab-grown marquise, ready to be cradled by a finely crafted 18K palladium white gold band.

Hand-forged in our Williamsburg studio, the band’s subtle sheen complements the diamond’s sharp geometry, while the halo setting amplifies brilliance without adding bulk. The low-profile design ensures everyday comfort, slipping easily beneath gloves or alongside stackable bands.

Each piece reflects a commitment to sustainability, featuring a lab-grown diamond that offers clarity and sparkle with a lighter environmental footprint. The cool palladium alloy lends durability and a modern white tone that resists tarnish, polished to a smooth finish that feels as refined as it looks.

Ideal for those who appreciate architectural elegance paired with artisanal detail, this ring suits slender to medium finger shapes, enhancing length with its tapered form. The semi-set option allows you to select a center stone that resonates personally, making the design uniquely yours.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care and customization options during your visit or online consultation.
