Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching the light as it elongates the hand with its tapered silhouette—an intimate moment of quiet brilliance. This semi-set platinum band awaits your choice of an 8 x 4 mm marquise center, designed to cradle the stone securely while maintaining a sleek, low-profile presence.

Crafted in Williamsburg, the platinum mounting is meticulously finished to a smooth comfort fit, ensuring it feels as natural as a second skin. The solitaire setting’s slender prongs elevate the diamond just enough to maximize sparkle without sacrificing everyday wearability.

Each lab-grown diamond offers clarity and fire with a fraction of the environmental impact, reflecting a commitment to ethical jewelry without compromise. The ring’s streamlined silhouette suits hands that appreciate refined elegance and can be effortlessly stacked or worn solo for understated grace.

Should you need resizing, our Brooklyn studio provides precise adjustments to maintain the ring’s balance and comfort. Lead times are tailored to your design choices, with attentive guidance throughout.
