Chinese puzzle ball mystery ball 4” nested carved balls lucky serpentine

Mesmerizing 4” green puzzle ball. Three carved balls inside each other. The name refers to the incredible craftsmanship it takes to create these works of art. I do not know if this is jade or soapstone. These “lucky” Chinese puzzle balls (also known as mystery balls) are traditionally carved out of wood, resin, ivory, or stone. EUC.
