Laser Settings for Granite
Can you laser engrave granite?
Yes — dark, polished granite gives some of the strongest light-on-dark contrast of any stone, which is why it's the staple for memorial plaques, house signs and awards. Diode and CO2 both mark it well; the darker the granite, the better the result.
