Sunlight catches the softly rounded corners of a 5 x 5 mm cushion-cut diamond, its gentle glow unfolding like a quiet promise. This platinum engagement ring is designed with a low-profile setting that nestles close to the finger, balancing presence with everyday comfort.

Crafted in Williamsburg, the band’s smooth finish and secure prong accents ensure durability without bulk, making it ideal for daily wear. The cushion shape offers a subtle vintage warmth, its softly faceted surface reflecting light with a tender, inviting shimmer.

Each diamond is lab-grown, chosen for clarity and ethical sourcing, reflecting a commitment to sustainability without compromise. The platinum setting enhances the stone’s natural brilliance while providing a hypoallergenic, resilient foundation.

Its streamlined silhouette suits a range of hand sizes and shapes, slipping easily beneath gloves or alongside stackable bands. The comfort fit band gently curves to the finger, inviting continuous wear through life’s moments.

Should you need resizing, our Brooklyn studio offers precise adjustments to maintain the ring’s integrity and comfort. Typical lead times reflect careful handcrafting and quality inspection.
