The invention provides a method for manufacturing a crystal image in a polishing-free way, belonging to the technical field of artware manufacture. The method is realized by the following technical scheme: printing an image onto a polishing-free crystal transfer film; sticking the polishing-free crystal transfer film onto a crystal blank, wherein the surface of the crystal blank is cleaned up before the transfer film is stuck; after the transfer film is stuck, putting the crystal blank into a crystal curing machine for curing; taking out the cured crystal image, and removing the redundant parts of the crystal transfer film. According to the method for manufacturing the crystal image in the polishing-free way, after the image is printed onto the polishing-free crystal transfer film, the polishing-free crystal transfer film is stuck on the crystal blank by ultraviolet (UV) crystal glue, the crystal blank is cured by the curing machine, and the redundant edges of the transfer film are cut off by an art knife, so that the method is simple and rapid in operation, and saves time and labor. Furthermore, sticking and curing are only carried out for once, so that the consumption of the UV glue is less; the manufactured crystal is very high in transparency.
