Lab-Grown Diamond Engagement Ring

Sunlight catches the 9 mm round lab-grown diamond at the center, scattering light like a quiet Brooklyn afternoon. This platinum engagement ring balances presence with subtlety, its low-profile setting designed to sit comfortably beneath daily gloves and sleeves.

Crafted in Williamsburg, the band’s smooth finish and secure prong setting ensure durability without bulk. The round diamond’s classic brilliance is enhanced by delicate accent stones that add a refined shimmer without overwhelming the design.

Each diamond is ethically sourced from the lab, offering clarity and sparkle with a significantly reduced environmental footprint. The platinum band’s weight and cool touch provide a reassuring feel, ideal for those seeking a ring that moves seamlessly from morning coffee to evening plans.

Its streamlined silhouette suits a variety of hand shapes and sizes, making it a versatile choice for stacking or solo wear. The comfort fit band gently hugs the finger, minimizing irritation during long wear.

Should you need resizing, our in-studio experts handle adjustments with care, ensuring the ring maintains its integrity and finish.
