Several samples of geological stones from statuary pedestals found in various archaeological sites in Cyprus have been characterized using non‐contact laser infrared photothermal radiometry. Thermal diffusivities and effective optical absorption coefficients were calculated using a one‐dimensional thermal‐wave model. The mean values and standard deviations were tabulated and comparisons were made with lithographic and petrographic studies of the samples. Good correlations were found, thus demonstrating that laser photothermal archaeometry is a promising methodology for the accurate, potentially non‐destructive and convenient characterization of the origins of ancient stones in Cyprus and other geological and archaeological sites.
