In the Period III crafts show marked development; lapis lazuli, turquoise and carnelian were worked into beads with green cylindrical jasper drills. The jasper bits of this period are the earliest specimen known of a type that was used later during the third millennium BC at Shahr-i-Sokhta, Shahdad and at Chanhu-Daro. These are some very fine micro-drills indicating the use of low-drills working and engraving ornaments in shell.
