Lab-Grown Diamond Engagement Ring

When light catches the soft curves of a heart-shaped diamond, it unfolds a quiet story of devotion and delicate artistry. This semi-set engagement ring features an 18K yellow gold band, hand-forged in our Williamsburg studio to cradle a 10 x 10 mm heart diamond with a halo of meticulously placed pavé stones, amplifying its radiant silhouette.

The band’s warm gold hue is polished to a satin finish, offering a subtle contrast to the diamond’s brilliance while maintaining a comfortable, low-profile fit that slips easily beneath a wedding band or stack. Each prong is carefully shaped to secure the stone without overwhelming its tender form, reflecting our artisan approach to balance and wearability.

Crafted with a lab-grown diamond, this ring embodies a commitment to ethical jewelry—minimizing environmental impact while delivering exceptional clarity and sparkle.

Designed for those who appreciate romantic symbolism paired with everyday elegance, the heart shape elongates the finger with its gentle point and rounded lobes, making it a striking yet approachable choice. Its halo setting enhances light reflection, perfect for hands that favor a refined but expressive statement.
