Lab-Grown Diamond Engagement Ring
Sunlight catches the sharp edges of a 4 x 4 mm square diamond, its precise geometry casting a confident, architectural glow. This semi-set engagement ring invites you to select a center stone that reflects your personal clarity and style.
Crafted from warm 14K rose gold, the mounting’s clean lines and subtle accents balance modern minimalism with structural elegance. The band’s smooth finish and low-profile setting ensure comfortable daily wear, while the secure prongs frame your chosen diamond with quiet strength.
Each piece is thoughtfully made in Williamsburg, Brooklyn, where our studio’s commitment to sustainable practices includes exclusively lab-grown diamonds—offering brilliance without compromise.
Designed for those who appreciate refined geometry and understated confidence, this ring pairs effortlessly with stackable bands or stands alone as a statement of clarity. Its moderate size and comfort fit make it glove-friendly and ideal for everyday life.
Should you need adjustments, resizing is handled delicately in-studio to maintain the ring’s structural integrity and finish.
