Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a glassy, architectural shimmer that feels both deliberate and serene. This semi-set platinum mounting awaits a 10 x 8 mm emerald-shaped center, designed with clean lines and subtle accent stones that enhance the diamond’s clarity and structure without distraction.

Crafted in Williamsburg, the band’s low-profile setting ensures the ring sits comfortably against the finger, while the polished platinum offers a cool, weighty feel that balances modern minimalism with everyday wearability. Each piece is meticulously finished and inspected in-studio, reflecting a quiet confidence in its precision.

Choosing a lab-grown diamond here means embracing a clearer conscience alongside clarity of cut—ethical jewelry made with sustainability in mind, without compromise on brilliance.

This design suits those who appreciate architectural elegance and want a ring that layers effortlessly with other bands or stands alone with quiet strength. Its streamlined silhouette fits well on slender to medium fingers and slips easily under gloves or sleeves.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the integrity of the setting and finish.
