Lab-Grown Diamond Engagement Ring

Sunlight catches the delicate curve of a round diamond, its facets whispering quiet brilliance against the warm glow of 18k yellow and 18k yellow and platinum and the cool gleam of 18k yellow and platinum. This semi-set engagement ring offers a refined foundation, ready to cradle a 4.0–4.1 mm lab-grown diamond in a classic six-prong setting that balances security with light’s full dance.

Crafted in Williamsburg, the band’s comfort fit gently embraces the finger, its low-profile silhouette designed for everyday grace and ease. The fixed two-tone contrast between 18k yellow and 18k yellow and platinum and 18k yellow and platinum prongs creates a subtle interplay of warmth and coolness, enhancing the diamond’s sparkle without overwhelming it. Each ring is meticulously finished and inspected by hand, ensuring a smooth edge and flawless polish.

Choosing a lab-grown diamond aligns with a commitment to ethical jewelry, reducing environmental impact while celebrating clarity and brilliance. This ring suits those who appreciate understated elegance and a design that layers beautifully with wedding bands or stackable rings.

Resizing is available to ensure a perfect fit, crafted with the same care as the original design. Whether you visit our Williamsburg studio or explore custom design online, this semi-set ring invites you to begin a personal journey toward a uniquely meaningful symbol.
