Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 6 by 3.5 millimeters, draws the eye along the finger with a subtle, tapered elegance. This solitaire semi-set ring offers a streamlined foundation crafted from warm 18K rose gold, designed to cradle your chosen stone with precision and a low-profile setting that sits close to the skin for everyday comfort.

Each band is hand-finished in our Williamsburg studio, polished to a gentle sheen that complements the diamond’s sharp facets without overwhelming its shape. The mounting’s secure prongs ensure stability while maintaining a sleek profile, ideal for those who prefer a ring that moves seamlessly with daily life.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

With its slender band and modest height, this semi-set ring suits a variety of hand sizes and shapes, especially elongating fingers with its marquise outline. Its minimalist design pairs effortlessly with stacking bands or stands alone as a refined statement.
