Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This three-stone semi-set ring in 18K yellow gold offers a warm embrace, the center stone’s 7 x 3.5 mm shape balanced by two gently tapering side stones, creating a subtle narrative of connection and flow.

Handcrafted in Williamsburg, the band is polished to a soft luster and designed with a low-profile setting that rests comfortably against the skin, ideal for daily wear without catching. Each prong is meticulously finished to secure the stones while allowing maximum light to animate their facets, revealing the marquise’s signature brilliance and graceful geometry.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and sparkle with a smaller environmental footprint. This ring suits those who appreciate refined romance and a silhouette that elongates the hand, pairing effortlessly with stackable bands or worn solo as a statement of enduring affection.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as the moment it represents. Explore this semi-set design in our Williamsburg studio or begin your custom journey online, where expert guidance awaits.
