A method and device for manufacturing a bevelled stone, particularly for a timepiece are disclosed. A precursor is produced from a mixture of at least one material in powder form with a binder. The method includes pressing the precursor so as to form a green body, using a top die and a bottom die comprising a protruding rib, sintering the green body so as to form a body of the future stone in at least one material, the body including a peripheral face and a bottom face provided with a groove, and machining the body including a substep of planning the peripheral face up to the groove, such that an inner wall of the groove forms at least a flared part of the peripheral face of the stone.

According to a processing method of a stone composite board, the two sides of a natural stone board are ground and flattened until a preset standard value of thickness variation is reached, then the surface planes and base material layers are subjected to pressure-compositing through adhesive layers, afterwards splitting is conducted, and the natural stone layer is subjected to calibrated planing with diamond roller and surface treatment to obtain the ultra-thin stone composite board.
