Method for cutting crystal boules using diamond wire, wherein this boule is driven about a main axis, a cutting wire is held taut and driven through a temporary drum immobilising each boule in position with respect to the main axis throughout the entire cutting operation, this temporary drum being made by overmoulding a coating material on at least one boule bonded onto a sacrificial core, the cutting being followed by the slicing of cut rings from which are detached, particularly using heat, crystalline plates with parallel faces.
