Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, a 12 mm round lab-grown diamond catches every glance with quiet brilliance. This halo setting amplifies the diamond’s fire, surrounding it with a delicate circle of shimmering accents that dance with each movement.

Crafted in cool platinum, the band offers a smooth, comfort fit that feels like a natural extension of the hand. The low-profile halo setting balances presence with practicality, designed for daily wear without catching or discomfort. Each ring is meticulously finished by hand in our Brooklyn studio, ensuring precise prong work and a polished surface that reflects light from every angle.

Our diamonds are ethically cultivated in controlled environments, reducing environmental impact while delivering exceptional clarity and sparkle.

This ring suits those who appreciate a blend of classic radiance and modern craftsmanship—its generous center stone elongates the finger, while the halo adds a whisper of vintage romance. The platinum band’s subtle heft grounds the design, making it ideal for stacking or wearing solo with understated elegance.

Should you need a custom fit, resizing is handled expertly in-studio to maintain the ring’s integrity and comfort.
