This spruce is very old. It was collected by myself in Italy in 1993. The stone has two tow very good sides. I took the one with the deeper holes for the long termm health of the tree. After the first arrangement was photographed I carried the stone to my exhibit area and it broke apart as I carreid it. What a mess. Well, now I have two stones: a large one which was used for the same spruce right away and a smaller one for future use. I liked it better before. But such is bonsai. Sh..t happens.
