Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch the hand with quiet elegance. This three-stone semi-set ring in warm 14K rose gold offers a handcrafted foundation ready to cradle a 9 x 4.5 mm marquise center stone, its shape evoking vintage allure with a modern edge.

Each band is meticulously shaped and polished in our Williamsburg studio, the rose gold’s soft blush complementing the diamond’s fiery facets. The three-stone setting balances presence with wearability, designed for a low-profile fit that slides comfortably beneath gloves or rings stacked alongside it. Our artisan finish ensures smooth edges and a comfort fit that invites daily wear without fuss.

Crafted exclusively for lab-grown diamonds, this ring reflects a commitment to ethical jewelry—minimizing environmental impact while maximizing brilliance and clarity. The semi-set format allows you to select a center stone that speaks to your personal story, with expert guidance available to help you find the ideal cut and quality.

Ideal for those who appreciate architectural grace and subtle romance, this ring suits slender to medium finger shapes, enhancing length and light with its tapered marquise form. Resizing is straightforward, handled with care in-studio to preserve the ring’s integrity.
