Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set halo engagement ring in 18K rose gold frames a 6 x 3.5 mm marquise center stone, ready to be chosen and set with your ideal lab-grown diamond.

The warm blush of rose gold complements the marquise’s vintage-inspired shape, while the halo setting amplifies its light with a subtle circle of smaller stones, enhancing brilliance without overwhelming. Crafted with a low-profile design, the band offers a comfortable fit that sits close to the finger, ideal for daily wear and effortless stacking.

Each ring is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every curve and prong to ensure a seamless silhouette and secure setting. The semi-set approach invites personal choice, allowing you to select a lab-grown diamond that reflects your unique story with clarity and conscience.

Lab-grown diamonds provide the same optical beauty as mined stones but with a lighter environmental footprint, aligning with a modern ethos of ethical jewelry. The slender shape of the marquise lends itself beautifully to elongating the hand, flattering a range of finger sizes and shapes.

Should you need adjustments, resizing is available to ensure your ring fits perfectly. Typical lead times reflect our commitment to handcrafted quality rather than mass production.
