Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 5 x 5 mm cushion diamond, its gentle glow poised to become the heart of a three-stone ring. This semi-set foundation in warm 10K yellow gold awaits your choice of center stone, crafted with a low-profile bezel setting that nestles comfortably against the finger.

Each band is hand-finished in our Williamsburg studio, where artisan techniques refine the smooth comfort fit and ensure the prongs cradle side stones securely without excess height. The subtle curve of the shank balances everyday wearability with elegant presence.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance that honors sustainability without compromise. The ethical origin of your stones reflects a modern approach to fine jewelry, rooted in care for both craft and planet.

This design suits those who appreciate understated sophistication—its low profile slips easily beneath gloves and stacks gracefully with wedding bands or accent rings. The cushion shape’s soft vintage glow complements a variety of hand shapes, offering a quiet statement of refined taste.

Should you need resizing or guidance on selecting the perfect center diamond, our Brooklyn studio team is ready to assist with thoughtful, pressure-free advice.
