Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 5 x 5 mm cushion diamond, its gentle glow framed by two smaller stones that balance presence with quiet elegance. This three-stone semi-set in platinum offers a modern-minimal silhouette, where clean lines and structural clarity meet refined confidence.

Crafted in Williamsburg, the platinum band is polished to a satin finish that feels cool and substantial against the skin, designed for daily wear with a low-profile setting that slips easily beneath gloves or layered rings. Each prong is meticulously shaped to cradle the center stone securely while allowing light to dance freely through its facets.

The diamonds are lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Ideal for those who appreciate architectural simplicity with a touch of classic romance, this ring complements slender to medium finger sizes and pairs effortlessly with stackable bands or wedding bands of similar metal weight.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a comfortable fit without altering the ring’s clean lines.
