Sunlight catches the gentle curves of an 11 x 11 mm cushion-cut diamond, its soft corners glowing with a quiet fire. This platinum engagement ring is designed for everyday elegance, its low-profile setting ensuring the stone sits close to the finger, minimizing snagging while maximizing comfort.

Crafted in Williamsburg, Brooklyn, the band’s smooth finish and secure prong setting reflect meticulous hand inspection, balancing durability with refined detail. The platinum’s cool tone enhances the diamond’s warm brilliance without distraction.

Each diamond is lab-grown, offering a clear, sustainable choice that honors both beauty and conscience. The cushion shape’s rounded edges and generous facets create a vintage-inspired glow that feels intimate yet modern.

Ideal for those who appreciate a substantial presence without bulk, this ring fits comfortably beneath gloves and pairs seamlessly with stackable bands. Its thoughtful proportions suit a variety of hand sizes, offering a confident yet understated statement.

Resizing is available to ensure a precise fit, with careful adjustments made in-studio to maintain the ring’s structural integrity.
