Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 6 x 6 mm square lab-grown diamond, its halo of smaller stones amplifying a quiet architectural brilliance. This platinum engagement ring balances precision with comfort, featuring a low-profile halo setting that nestles close to the finger for everyday wear without catching.

Handcrafted in Williamsburg, Brooklyn, the ring’s platinum band is polished to a satin finish that resists scratches while maintaining a refined glow. The halo setting is meticulously secured with micro-prongs, ensuring durability and a seamless silhouette that complements the square center’s geometric clarity.

Each diamond is ethically sourced from a lab-grown process, reducing environmental impact while delivering exceptional clarity and sparkle. The cool platinum metal enhances the stone’s icy facets, creating a modern yet timeless statement.

Designed for those who appreciate clean lines and subtle sophistication, this ring fits comfortably beneath gloves and stacks effortlessly with other bands. Its balanced proportions suit a variety of hand shapes, offering a confident presence without overwhelming the wearer.

Resizing is available through our Brooklyn studio, where every adjustment preserves the ring’s structural integrity and finish. Typical lead times reflect our commitment to careful craftsmanship and personalized attention.
