For those who want to keep it minimal but still pack a punch... these medium sized moonballs complement the rest of the collection without overwhelming the other pieces.  These perforated spheres are the same size as the medium moonball ring- approximately 14mm in diameter.

The moonballs are made from 3D printed stainless steel infused with bronze and hang from sterling silver hooks.  The steel balls can also be plated in 24K gold (with gold-filled hooks) or in antique bronze (with oxidized sterling silver hooks).
