Lab-Grown Diamond Engagement Ring

Sunlight catches the three round diamonds, each poised to catch the eye with a quiet brilliance that feels both intimate and expansive. This semi-set engagement ring foundation in 18K yellow gold invites your choice of a 12 mm center stone, framed by two smaller companions that balance presence with elegance.

Handcrafted in our Williamsburg studio, the band’s warm gold gleams with a soft polish, its subtle curvature designed for comfort and daily wear. The three-stone setting is sculpted to sit low against the finger, easing under gloves and stacking seamlessly with other bands.

Each lab-grown diamond offers clarity and sparkle without compromise, reflecting a commitment to sustainable luxury that honors both craft and conscience. The round shape, classic yet endlessly versatile, lends a lively fire that dances with every movement.

Ideal for those who appreciate a statement ring that remains grounded in everyday grace, this piece complements a variety of hand shapes and personal styles. Its thoughtful proportions ensure the ring feels balanced and secure, a tactile joy to wear.
