Lab-Grown Diamond Engagement Ring
Morning light catches the subtle sparkle of an 8.2 mm round diamond, poised to become the centerpiece of a carefully crafted engagement ring. This semi-set platinum mounting offers a sleek, low-profile silhouette designed for everyday wear, with delicate accent settings that enhance brilliance without bulk.
Each ring is hand-finished in our Williamsburg studio, where platinum’s cool weight is shaped for comfort and durability. The setting’s precision ensures the diamond sits secure yet unobtrusive, ideal for those who value a refined feel beneath the hand.
Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire.
With its balanced design, this mounting suits a variety of finger shapes and sizes, offering a comfortable fit that pairs well with stacking bands or a wedding ring. Its low profile also makes it glove-friendly and practical for daily life.
Should you need resizing or prefer a custom finish, our Brooklyn studio accommodates adjustments with care and expertise.
