Manufacturing Method of Jewelry for Jewelry of Jewelry

摘要

The present invention relates to a ring (11) jewelry that is given a pattern by processing the metal (111) of a noble metal and/or the plating layer (112) on the metal (111). Precious metal jewelry of the present invention, the plating layer 112 on the upper surface of the metal 111 is formed with a uniform thickness on the entire surface, the metal 111 and / or the plating layer 112, the rod-shaped polishing tool (12) As a result, glossy regions 111-1 and 111-2 to which the base metal 111 are exposed are formed. In the jewelry of the present invention, a metal region 112 in which a metal layer is exposed is formed as a region not polished at all by the rod-shaped polishing mechanism 12 . The manufacturing method of the precious metal jewelry of the present invention is controlled so that the precious metal jewelry grinds the base metal 111 and/or the metal plating layer 112 in a fine linear shape while changing the length, depth, and pitch in the line width direction differently. Therefore, since the light reflection of the metal plating layer 112 and the base metal 111 is different, compared with the pattern produced by the mask, the periphery of the pattern is not certain and different light reflection regions 113 are formed, It is manufactured as expensive precious metal jewelry.
