Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a glassy, architectural shimmer that draws the eye along its clean lines. This semi-set three-stone engagement ring foundation in platinum offers a sleek, modern-minimal silhouette, designed to frame a 10 x 8 mm emerald center stone of your choosing.

Crafted in Williamsburg, the platinum band is polished to a soft glow, its low-profile setting ensuring daily wearability without catching. The three-stone layout balances clarity and structure, with side stones enhancing the center’s linear elegance while maintaining a confident, uncluttered presence.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine brilliance with sustainability. The cool weight of platinum complements the emerald’s elongated shape, offering a comfortable fit that sits close to the finger and layers effortlessly with other bands.

Ideal for those who appreciate architectural refinement and understated strength, this mounting suits hands that favor clean geometry and a contemporary aesthetic. Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio.
