Lab-Grown Diamond Engagement Ring

Sunlight catches the softly rounded corners of an 8 x 8 mm cushion diamond, its gentle glow poised to become the centerpiece of a three-stone story. This semi-set engagement ring offers a 10K white gold foundation, hand-shaped and polished in our Williamsburg studio to a smooth, low-profile silhouette that rests comfortably against the skin.

The three-stone setting balances artisanal precision with everyday wearability: secure prongs cradle each gem, while the band’s subtle tapering invites effortless stacking or solo elegance. Finished with a comfort fit interior, the ring slides on with ease, designed for hands that move through daily life without fuss.

Each diamond is lab-grown, embodying clarity and brilliance without the environmental cost of traditional mining. This ethical choice reflects a quiet commitment to sustainability woven into every facet of our craft.

Ideal for those who appreciate a blend of classic form and modern conscience, the cushion shape lends a soft vintage glow that complements a variety of hand shapes and sizes. The semi-set design invites you to select a center stone that resonates personally, making the ring uniquely yours.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers personalized consultations to ensure a flawless fit and finish.
