FIELD: process engineering.
SUBSTANCE: invention relates to jewels production, particularly, to laser etching of images on articles from noble metals. In compliance with first version, article is polished to purity class of not over 9th and cleaned for the article to be fixed. Computer image is entered into laser radiator program unit and applied on article surface by laser beam tuned to point burning-through. Then, finished article is cleaned of carbon.
