Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a subtle glow that gently stretches across the hand. This semi-set platinum band awaits your choice of a 10 x 8 mm oval stone, its six-prong setting designed to showcase the gem’s graceful silhouette with modern clarity and structural precision.

Crafted from cool, polished platinum, the band offers a lightweight feel and a low-profile setting that rests close to the finger, ensuring everyday comfort without sacrificing presence. Each prong is meticulously shaped to secure the stone while maintaining an open view, allowing light to enter freely and enhance the diamond’s natural fire.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry—minimizing environmental impact while embracing exceptional clarity and brilliance. The oval shape’s gentle elongation flatters a variety of hand sizes, pairing effortlessly with stacking bands or worn solo for a confident, minimalist statement.

Should you need resizing, the platinum band can be adjusted with care to maintain its sleek form. We invite you to explore this semi-set design in our Williamsburg studio or begin your custom design journey online, where expert guidance meets thoughtful craftsmanship.
