Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of the marquise diamond, casting a slender, luminous silhouette that seems to stretch beyond the hand. This three-stone semi-set engagement ring in 18K yellow gold frames an 8 x 4 mm marquise center with two delicately balanced side stones, each chosen to enhance the graceful taper and subtle drama of the shape.

Crafted in Williamsburg, the band’s warm gold gleams softly, its polished finish smooth against the skin. The setting is designed with a low profile to sit comfortably beneath a glove or alongside stackable bands, making it an elegant choice for daily wear. Each prong is meticulously hand-set and inspected to secure the stones while allowing light to dance freely through every facet.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and brilliance, offering an ethical alternative without compromise. The marquise’s distinctive silhouette elongates the finger, ideal for those who appreciate a blend of vintage allure and modern refinement.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks. Lead times for custom finishing typically range from four to six weeks, allowing for careful craftsmanship without rush.
