Lab-Grown Diamond Engagement Ring

Sunlight catches the 12mm round diamond’s facets, scattering light like a quiet promise held close. This semi-set solitaire invites you to choose a center stone that will become a daily companion, its classic round cut offering a familiar brilliance that feels both intimate and enduring.

Crafted in warm 14K yellow gold, the mounting balances subtle warmth with a refined silhouette. The band’s gentle curve and low-profile setting ensure comfort beneath the hand, while the polished finish reflects the Brooklyn studio’s meticulous attention to detail. Each piece is hand-finished and inspected to meet exacting standards.

Our diamonds are lab-grown, offering clarity and sparkle with a mindful approach to sustainability and ethical sourcing.

This ring suits those who appreciate a timeless shape with modern ease—its slender band fits naturally alongside other stackable rings or stands alone with quiet confidence. The low profile makes it glove-friendly and ideal for everyday wear.
