Lab-Grown Diamond Engagement Ring

Light filters softly through a 12 x 12 mm cushion-shaped diamond, its gentle facets inviting a quiet moment of reflection. This semi-set solitaire ring in 18K white gold offers a foundation crafted for your choice of center stone, designed with precision to highlight the diamond’s subtle vintage glow.

The band’s low-profile setting sits close to the finger, balancing presence with everyday comfort. Expertly finished in Williamsburg, the smooth shank ensures a secure fit without bulk, ideal for those who prefer a ring that moves seamlessly with daily life.

Each piece embraces lab-grown clarity, reflecting a commitment to sustainable luxury without compromise. The cool white gold complements the cushion’s soft geometry, creating a refined silhouette that suits a variety of hand shapes and personal styles.

Its streamlined design lends itself well to stacking or wearing solo, while the semi-set format invites customization with your chosen diamond. Resizing is straightforward, handled carefully in-studio to maintain the ring’s integrity.
