Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise center stone, measuring 9 by 4.5 millimeters, draws the eye with its tapered drama and subtle hand-lengthening effect. This three-stone semi-set engagement ring features an 18K yellow gold band crafted for everyday grace, with a low-profile setting that nestles close to the finger for comfort and ease under gloves or alongside other rings.

Each element is meticulously finished in our Williamsburg studio, where the band’s smooth contours and secure prong work ensure durability without bulk. The semi-set design invites your choice of a lab-grown marquise diamond, known for its ethical clarity and sustainable origins, reflecting a commitment to responsible luxury.

Designed with daily wear in mind, the ring’s balanced proportions suit slender to medium finger shapes and stack effortlessly with complementary bands. Its low profile minimizes snagging, making it a practical yet elegant companion for life’s moments.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers expert fitting with attentive care. Typical lead times accommodate thoughtful customization without rush.
