A joint research between Italy and India was conducted in 2 marble quarries to compare the characteristics of the diamond wires used, through the analysis of their performance. The research had also the aim to exchange the know-how on the quarrying methods and cutting techniques: tests were carried out both on site and in laboratory, and the necessary data were collected. The sites under investigation were Carrara (Italy) and Ambaji (India). In both quarries the mixed technique “diamond wire saw and cutting chain” is used, but research has focused mainly on the performance of the wire. The following data were collected on the diamond wire saw to outline the performance of the system: installed power, cut geometry, cutting speed, wire length, tension applied to the wire, diameter of wire and beads, number of beads/meter. Moreover, samples both of marble and of overburden waste rocks were collected, needful to carry out the mechanical laboratory tests. Therefore, a characterization of the rock at different laboratory scales was done, to obtain data on rock-tool interaction, to evaluate the beads consumption and to develop guidelines for dimension stone cutting with diamond wire saw
