Abstract

DC60 (02/02/48) To make informative markings invisible on the cut surface of a diamond gem. The layer of antimicrobial agents were Coating throughout the exposed surface of the gem A layer of gold is coated on the cut surface in the area where the mark will be branded. Selected area of The metal and the preservative will be loosened. By loosening too An ultraviolet laser to make a projection frame on the surface, grinding, electroplating, metal impregnation. And the cut surface will also be eroded. The plasma passes through the projection frame to seal. The mark is of the optimum depth, then a layer of stabilizer and metal is removed (shapeless) to make the informative mark invisible on the cut surface of a diamond gem. The layer of antimicrobial agents were Glaze the open surface of the gem. The gold layer is coated on the surface. Cut in the area where the mark will be branded. Selected area of Metals and stabilizers are also loosened by loosening. An ultraviolet laser to make a projection frame on the grinding surface, electroplating, impregnation, and the grinding surface are eroded. The plasma passes through the frame to mark the mark at the optimum depth, then a layer of the dye and metal compound is removed (not shaped).
