Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that dances across the hand. This semi-set platinum band awaits your choice of a 12 x 6 mm marquise center, its sleek, low-profile setting designed to cradle the stone securely while allowing light to flood every facet.

Crafted in our Williamsburg studio, the platinum band is meticulously hand-finished to a smooth comfort fit, ensuring it rests lightly yet confidently for daily wear. The solitaire setting’s minimalist prongs elevate the diamond just enough to reveal its tapered drama without sacrificing practicality or glove-friendliness.

Each lab-grown diamond chosen for this ring reflects a commitment to ethical sourcing and sustainability, offering clarity and brilliance without compromise. The marquise shape’s distinctive pointed ends elongate the finger, making it an elegant choice for those who appreciate architectural form with a touch of vintage allure.

Ideal for someone seeking a statement piece that balances bold geometry with understated wearability, this mounting pairs beautifully with stackable bands or stands strikingly alone. Should you need resizing or guidance on selecting the perfect stone, our Brooklyn studio offers personalized support through every step.
