Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set engagement ring foundation in warm 18K yellow gold is crafted to cradle a 6 x 3 mm marquise center stone, offering a sleek, low-profile frame that slips comfortably beneath daily gloves or sleeves.

Hand-finished in our Williamsburg studio, the band’s subtle accents enhance the setting’s architectural balance without adding bulk. The smooth interior ensures a comfort fit, while the secure prong arrangement promises stability for everyday wear. Each piece undergoes meticulous inspection to meet exacting standards of craftsmanship.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry—minimizing environmental impact while maximizing clarity and brilliance.

This mounting suits those who appreciate refined geometry and a ring that integrates seamlessly with stacking bands or stands alone with quiet confidence. Its low profile and balanced proportions make it ideal for hands of all sizes, especially those seeking a modern yet understated engagement ring.

Resizing is straightforward, handled with care in-studio to preserve the ring’s integrity and finish. Typical lead times accommodate thoughtful customization without rush.
