The rough for these beautifully figured Jumbo Tumbled Stones comes from Madagascar.
The Jumbos made of Petrified Wood (tree quartz) are approx. 3,5 - 5,0cm big; per packing unit (=VE) with 0,5kg you get approx. 8 - 12 stones.
Jumbos are ideal for decorations as well as for use in stone healing applications, e.g. for stone circles and massages.
