Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a serene, glassy glow that draws the eye along its architectural lines. This semi-set platinum mounting awaits your choice of a 7.5 by 5.5 mm emerald stone, designed with a low-profile bezel that hugs the finger for everyday grace and ease.

Handcrafted in our Williamsburg studio, the ring’s platinum band is meticulously polished to a satiny finish, offering a cool, substantial feel that balances durability with refined comfort. The setting’s clean edges and secure bezel ensure the stone sits flush, minimizing snagging and complementing a modern, minimalist wardrobe.

Each diamond is lab-grown, embodying a commitment to sustainability without compromising on clarity or brilliance. This ethical approach aligns with our Brooklyn ethos—thoughtful, intentional, and rooted in craft.

Ideal for those who appreciate architectural elegance and a ring that integrates seamlessly with stacking bands or a wedding band. The comfort fit and modest height make it glove-friendly and suited for daily wear, especially on slender to medium fingers.

Should you need resizing or assistance selecting the perfect emerald, our studio offers personalized consultations to ensure your ring fits flawlessly and reflects your vision.
