Lab-Grown Diamond Engagement Ring

When light catches the sharp edges of a 10 x 10 mm square diamond, it fractures into a quiet symphony of brilliance—each facet a whispered promise. This five-stone semi-set ring invites you to choose a centerpiece that anchors a constellation of smaller companions, all cradled in cool 18K white gold.

Crafted with precision in Williamsburg, the band’s low-profile setting ensures the stones sit close to the finger, offering a sleek silhouette that balances presence with everyday comfort. The polished finish reflects subtle glimmers, while the secure prong work highlights the geometry without distraction.

Each diamond is lab-grown, embodying clarity and sustainability without compromise. This ethical foundation aligns with a modern commitment to responsible luxury.

Designed for those who appreciate architectural elegance paired with romantic detail, the square shape’s clean lines elongate the finger, while the five-stone arrangement adds depth and narrative. Its modest height makes it glove-friendly and ideal for stacking alongside a wedding band or personal heirlooms.

Should you need adjustments, resizing is handled delicately in-studio to maintain the ring’s integrity and finish. Typical lead times reflect the care invested in every custom piece.
