Petrified trees are made of silica, an element harder than granite.

In order to cut, we use a process which is at once economical in raw materials, can be adapted to deal with the most fragile pieces, allowing for great precision and also to work with very large pieces.



The cutting process is by wire. It is a method which has been more or less abandoned in stone cutting, but perfectly adapted to work on silicified wood.

It takes approximately one day to cut through one square metre of petrified wood.

Petrified wood, particularly from Arizona, is so hard that the cable has to be changed after each significant cut.
