Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 15mm cushion diamond, its halo of delicate pavé stones amplifying a gentle vintage glow. This semi-set engagement ring invites you to select a center stone that balances architectural warmth with a whisper of old-world charm.

Crafted from 18K white gold, the band is hand-finished in our Williamsburg studio to a smooth, comfort-fit profile that rests lightly on the finger. The low-profile halo setting offers subtle sparkle without catching on daily fabrics, designed for wear that moves seamlessly from morning light to evening shadows.

Each ring is a quiet testament to sustainable luxury, featuring a lab-grown diamond foundation that reflects a commitment to ethical sourcing and environmental mindfulness.

Ideal for those who appreciate a blend of artisan detail and modern ease, this ring complements slender to medium finger shapes and layers beautifully with stackable bands or a wedding band of your choice.

Should you need resizing or guidance on selecting the perfect cushion diamond, our Brooklyn studio team is ready to assist with care and expertise.
