ABSTRACT:
A method of forming an artificial diamond, comprising applying a laser beam to a glassy solid carbon material, while moving a point on the glassy solid carbon material at which the laser beam is applied, to form a locally fused portion thereon, whereby every part of the locally fused portion is cooled as the point moves away therefrom. During cooling of the locally fused portion, an artificial diamond is formed in adjacent regions on both sides of the solidified locally fused portion.
