Lab-Grown Diamond Engagement Ring
Sunlight catches the gentle curve of an 8.2 mm round diamond, poised to become the heart of your story. This semi-set platinum band awaits your choice of center stone, crafted with a low-profile setting that embraces daily wear without catching or lifting.
Each band is meticulously forged in our Williamsburg studio, where the cool weight of platinum is hand-finished to a satin sheen, accented with delicate artisan details that frame the center stone with subtle brilliance. The comfort fit ensures the ring settles naturally on the finger, ideal for stacking or wearing solo.
Our commitment to lab-grown diamonds means your ring carries clarity and sparkle with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.
Designed for those who appreciate understated elegance, this mounting suits a variety of hand shapes, its balanced proportions enhancing the diamond’s classic round fire. The low profile makes it glove-friendly and perfect for everyday life.
Should you need resizing, our in-house experts handle adjustments with care to maintain the integrity of the setting.
