Chalcolithic communities relied heavily on specialized stone technologies alongside copper. They mass-produced specialized blade-flake microliths (crested-ridge blades, lunates, trapezes) for agricultural sickles and domestic butchering. Simultaneously, expert craftsmanship produced ground stone axes, querns, and polished beads from agate, jasper, and chalcedony at sites like Inamgaon and Navdatoli.
