Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate dance of light and shadow. This semi-set halo engagement ring in 18K yellow gold frames a 10 x 5 mm marquise center, inviting you to envision the perfect stone that will complete its embrace.

Crafted with meticulous attention in our Williamsburg studio, the halo setting amplifies the diamond’s graceful shape, while the warm yellow gold band offers a smooth, comfort-fit profile designed for everyday wear. The low-profile mounting ensures ease beneath gloves or alongside stackable bands, blending seamlessly into a life lived fully.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that balance brilliance with sustainability.

Ideal for those drawn to romantic geometry and subtle drama, this ring suits slender fingers and complements elongated hand shapes, enhancing natural elegance without overwhelming.
