A 19th century Cantonese carved ivory concentric puzzle ball, diameter +/- 5.5 cm. CONDITION REPORT: The ball would appear to be in generally very good condition. We can see no evidence of any cracks to the outer sphere. All interior spheres appear to move as they should. Clearly it is difficult to inspect every section of the piece but there does not appear to be any significant internal damage with only very small cracks being visible.
