Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, a 9mm round lab-grown diamond catches the eye with a quiet brilliance, framed by a delicate halo that whispers of devotion. The platinum band, cool and substantial, cradles the stone in a low-profile setting designed for everyday grace and ease.

Each ring is meticulously crafted in our Brooklyn studio, where the halo setting is hand-finished to enhance the diamond’s fire without overwhelming its natural sparkle. The comfort-fit shank ensures a gentle embrace on the finger, making it as wearable as it is captivating.

Our diamonds are grown with care, offering clarity and brilliance while honoring sustainable practices that matter. This ring suits those who appreciate refined elegance with a modern edge—its silhouette balances presence and subtlety, ideal for stacking or solo wear.

Should you need a custom fit, resizing is handled expertly in-house to maintain the ring’s integrity. We invite you to explore this piece in person at our Williamsburg studio or begin your custom design journey online, where thoughtful craftsmanship meets your vision.
