Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This three-stone semi-set ring offers a foundation for a 6 x 3.5 mm marquise center, poised between two delicate side stones to amplify its sculptural presence.

Crafted from 18K white gold, the mounting balances strength with refined elegance, its slender prongs and smooth band shaped in our Williamsburg studio for daily wear. The low-profile setting ensures comfort beneath gloves or alongside stackable bands, while the polished finish reflects Brooklyn’s artisanal spirit.

Each lab-grown diamond is chosen for clarity and brilliance, embodying an ethical approach that reduces environmental impact without compromising radiance. The semi-set design invites you to select a center stone that resonates personally, making this ring a truly bespoke expression.

Ideal for those who appreciate architectural form and subtle drama, the marquise shape elongates the finger with a vintage-inspired edge, while the three-stone layout symbolizes past, present, and future. Its wearability suits hands seeking both statement and ease.

Resizing is available to ensure a precise fit, with care instructions provided to maintain the ring’s luminous finish over time.
