This is an unusual Chinese Jade Puzzle Ball with 3 layers. It is carved from a whole peice of Jade. Each of the layers move independently from one another. The outer sphere is 5.1cm (2") in diameter and 0.5cm(0.2") in thickness. The next inner layers are spherical in shape, also with holes, and are about 0.5cm in thickness. The final visible layer, right in the centre, has flat faces and appears almost hexagonal in shape. This beautiful puzzle ball comes with its own wooden stand. Please note as this is real jade, the puzzle ball you receive may differ slightly in colour from the picture shown. Be sure to add me to your favourites list! Check out my other items!
