Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate shimmer that dances with every movement. This three-stone semi-set engagement ring features an 8 x 4 mm marquise center, poised to elongate the finger with its tapered drama and refined elegance.

Crafted from 18K white gold, the mounting is shaped with precision to cradle the center stone securely while balancing two smaller side gems, enhancing the ring’s architectural flow. The band’s subtle curvature and polished finish offer a comfortable fit that sits low against the hand, making it ideal for daily wear without catching or discomfort.

Each piece is meticulously hand-finished in our Williamsburg studio, where artisans inspect every facet and prong to ensure a seamless union of form and function. The semi-set design invites you to select a lab-grown diamond of your choice, reflecting a commitment to ethical sourcing and sustainability without compromising brilliance.

Its slender profile and classic three-stone layout suit those who appreciate a blend of vintage-inspired drama and modern craftsmanship. The ring pairs effortlessly with stacking bands or stands alone as a statement of quiet sophistication.
