In the paper, results of the research oriented at the evaluation of possibility to use pulsating water jets for ornamental stone surface treatment are presented. Three different types of rocks (granite, basalt, and marble) were exposed to flat pulsating water jets during the tests. Characteristics of rock surfaces created by acting of pulsating water jets were compared to those created by traditional methods, namely polishing, bush hammering and flaming. Results obtained up to now indicate that the application of pulsating water jets in surface treatment of ornamental stones can reduce (or even eliminate) disadvantages of traditional techniques because it creates surface with required roughness but preserves its aesthetical appearance.
