Lab-Grown Diamond Engagement Ring
Sunlight catches the soft, rounded corners of a 9 x 9 mm cushion diamond, its halo setting amplifying a gentle glow that feels both intimate and assured. This semi-set platinum band awaits your choice of center stone, crafted with a low-profile design that slips comfortably beneath a sleeve or glove.
Hand-forged in Williamsburg, the platinum band balances durability with refined polish, its halo setting meticulously aligned to enhance light reflection without adding bulk. The secure prongs and smooth interior ensure a comfort fit designed for everyday wear, while the semi-set style invites personal selection of a cushion-cut diamond known for its vintage-inspired warmth and subtle sparkle.
Each lab-grown diamond option embodies clarity and sustainability, reflecting a commitment to ethical jewelry without compromise. The ring’s streamlined silhouette suits those who appreciate a blend of classic form and modern practicality, ideal for stacking or solo wear.
Resizing is straightforward, handled in-studio with care to maintain the band’s integrity and finish. Lead times vary slightly depending on stone choice, with personalized consultations available to guide your selection.
