Lab-Grown Diamond Engagement Ring

When light catches the curves of a heart-shaped diamond, it whispers a quiet promise of devotion. This semi-set three-stone engagement ring invites you to choose a 10 x 10 mm center stone that will pulse with personal meaning.

Crafted in warm 18K yellow gold, the band’s gentle curve and smooth finish cradle the stones with a low-profile setting designed for everyday grace. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring a secure yet delicate embrace that feels balanced on the finger.

Our commitment to lab-grown diamonds means your ring carries clarity and brilliance without compromise, reflecting a thoughtful approach to ethical jewelry.

The three-stone design suits those who appreciate symbolic layering—perfect for stacking or wearing solo, its comfort fit complements slender to medium finger shapes with ease. The heart shape’s romantic silhouette elongates the hand subtly, making it a natural choice for a meaningful statement.
