Laser marking has become the standard for permanent, high-resolution marking of jewelry. This guide explains how it works, where it fits in production, and how to choose the right marker.
How laser marking works
A focused fiber laser beam alters the metal surface to create high-contrast marks. Because the process is contactless, there is no tool wear and no mechanical stress on small or thin jewelry components.
Marking, engraving and cutting
Lower power settings produce fine surface marks and logos; higher power and slower speeds create deep engraving; the highest-power fiber sources can perform light cutting of thin metal.
Choosing laser power
For logos and serial numbers, 20–30 W is typically sufficient. For deep engraving on rings and tags, 50–70 W is common. 100 W enables light cutting in addition to deep marking.
Software and file types
Most markers support EzCad and LightBurn and accept common vector and raster formats, which makes it straightforward to import logos, monograms and batch serial numbers.
