Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a sleek, modern line. This platinum engagement ring frames a 12 x 6 mm marquise center with delicate accent stones, balancing architectural clarity with subtle sparkle.

Handcrafted in Williamsburg, the ring features a low-profile setting that sits close to the finger, ensuring comfort for daily wear. The platinum band is meticulously polished to a soft sheen, its cool tone enhancing the diamond’s crisp facets. Each accent stone is precisely set to complement the center’s dramatic shape without overpowering it.

Crafted with a lab-grown diamond, this piece reflects a commitment to ethical sourcing and sustainability, offering brilliance without compromise. The marquise cut’s elongated form naturally flatters slender fingers and pairs effortlessly with stacking bands or a wedding band.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the platinum’s luster and the diamond’s fire over time.
