Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 7 by 3.5 millimeters, casts a subtle yet striking presence, its tapered points drawing the eye along the finger’s natural line. This semi-set halo engagement ring foundation in warm 18K yellow gold offers a low-profile design crafted for everyday grace and comfort.

Each band is hand-finished in our Williamsburg studio, polished to a smooth comfort fit that slips on easily beneath gloves or rings stacked alongside it. The halo setting, designed to cradle the center stone securely, enhances the marquise’s signature brilliance without adding bulk, making it an ideal choice for those seeking refined wearability.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, ensuring clarity and sparkle with a reduced environmental footprint.

This ring suits those who appreciate architectural elegance paired with practical design—its slender profile complements slender and average finger sizes, while the halo setting adds a touch of luminous detail without overwhelming daily activities.

Should you need resizing, our in-house artisans provide precise adjustments to maintain the ring’s balance and comfort.
