Lab-Grown Diamond Engagement Ring

Sunlight catches the broad facets of an 11 x 9 mm emerald-cut diamond, casting a glassy, architectural shimmer that feels both bold and refined. This semi-set platinum solitaire ring offers a sleek foundation, hand-finished in Williamsburg’s artisan workshops to highlight the stone’s elongated elegance.

The low-profile setting ensures the ring sits close to the finger, crafted with a comfort fit band that balances presence with everyday ease. Each platinum surface is meticulously polished and inspected, reflecting a quiet strength beneath its modern geometry.

Choosing a lab-grown diamond means embracing clarity and sustainability without compromise—an ethical choice that aligns with mindful craftsmanship.

Designed for those who appreciate clean lines and a statement silhouette, this solitaire suits hands that favor architectural shapes and a refined yet wearable profile. Its streamlined form pairs effortlessly with stacking bands or stands strikingly alone.

Should you need a custom size, resizing is handled delicately in-studio to preserve the ring’s integrity and finish.
