Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand, where a marquise diamond’s tapered points catch light with quiet drama. This semi-set engagement ring foundation in 18K yellow gold awaits your choice of a 10 x 5 mm marquise center, designed to showcase the stone’s distinctive brilliance and elegant silhouette.

Crafted with a low-profile setting, the band offers a smooth, comfortable fit that sits close to the finger, ideal for everyday wear. The yellow gold’s warm glow complements the marquise’s sharp geometry, while the mounting’s precise prongs ensure secure placement without excess bulk.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity and sustainability without compromise. The semi-set style invites personalization, allowing you to select a center stone that resonates with your vision.

Its streamlined design suits those who appreciate refined details and a ring that layers effortlessly with other bands or stands confidently alone. The low profile also makes it glove-friendly and unobtrusive for daily routines.
