Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo engagement ring in 18K yellow gold frames a 10 x 5 mm marquise center, ready to be paired with a stone of your choosing.

Crafted with a low-profile setting, the halo gently embraces the center without adding bulk, ensuring comfort for everyday wear. The polished yellow gold band is shaped for a smooth fit, balancing elegance with practicality. Each element is meticulously finished in our Williamsburg studio, where precision meets quiet durability.

Our lab-grown diamonds offer a clarity and brilliance that honors both beauty and sustainability, reflecting a commitment to ethical jewelry without compromise.

Designed for those who appreciate refined geometry and a ring that sits close to the hand, this halo mounting complements slender fingers and pairs well with stacking bands. Its modest height makes it glove-friendly and ideal for daily life.

Should you need resizing or prefer a custom consultation, our Brooklyn studio welcomes you to explore options with no pressure and full transparency.
