Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow that dances across the hand. This semi-set halo engagement ring in 18K yellow gold frames an 8 x 4 mm marquise stone with delicate pavé accents, enhancing its graceful taper and vintage allure.

Crafted in Williamsburg, the band is polished to a soft glow and designed with a low-profile setting that sits comfortably beneath the finger, ideal for daily wear. Each prong is meticulously finished to secure the stone while allowing light to flood its facets, revealing the marquise’s signature brilliance and subtle fire.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and ethical origin, offering a conscious alternative without compromise. The warm yellow gold complements the marquise’s elongated shape, flattering slender fingers and pairing effortlessly with stacking bands or wedding rings.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s delicate balance. Lead times for custom settings typically range from four to six weeks, ensuring thoughtful craftsmanship.
