Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along its tapered points, creating a subtle sense of movement and grace. This semi-set engagement ring frame in 14K yellow gold offers a refined foundation for a 9 x 4.5 mm marquise center stone, designed with delicate accent details that enhance its architectural elegance without overwhelming the profile.

Crafted for everyday wear, the setting sits low against the finger, balancing presence with comfort. The band’s smooth finish and precise prong work ensure the diamond is secure while maintaining a sleek, unobtrusive line that slips easily beneath gloves or rings stacked alongside it. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of fit and finish.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, which offer exceptional clarity and brilliance with a smaller environmental footprint.

This ring suits those who appreciate a blend of classic form and modern practicality—ideal for hands that favor elongated shapes and a low-profile setting that complements an active lifestyle. The semi-set design allows you to select a marquise diamond that resonates personally, ensuring a truly custom expression.

Resizing is available to ensure a comfortable fit, and our team is happy to guide you through the selection and design process, whether in-studio or online.
