Lab-Grown Diamond Engagement Ring

Sunlight catches the broad facets of an emerald-cut diamond, casting a glassy, architectural shimmer that feels both modern and quietly commanding. This semi-set three-stone ring foundation in 10K yellow gold awaits your choice of a 10 by 8 mm center stone, designed to frame the elongated elegance of the emerald shape with two smaller side gems.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a smooth interior and a low-profile setting that sits close to the finger, making it ideal for daily wear. The artisan finish reveals subtle hammer marks and polished edges, a testament to the careful handwork behind each piece.

Each ring is designed around a lab-grown diamond, chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise on brilliance or character.

The slender band complements a range of hand sizes and pairs effortlessly with stacking rings or a wedding band, while the low profile ensures it slips easily under gloves or sleeves.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without disrupting the ring’s balance.
