I drew a leaf from my oak tree, the one at the back of the garden, I don't know what species it belongs to, but this leaf is made of ebony on a silver chain ...

This 5.6 cm long pendant was entirely hand carved from ebony by a Tuareg craftsman. 

It was then mounted on a solid silver chain 70cm in total length. 

Its weight is 7 grams. It's soft in the palm of your hand and you never tire of playing with it!
