A necklace of thirty-seven rock crystal (quartz) beads of graduating size from the Swat Valley region of what is now northern Pakistan. The beads are mostly ground to a six sided shape, wide at the center with pointed ends, but some of them are rectangular solids as well. The largest bead at the center-point is 2.55 cm in length, 1.72cm in width and with a drill hole diameter of 2.7mm. The beads are 2,000 years old. There are some unusual features to the beads in this necklace. The fifth bead from the back on the right side is a natural crystal spar that has been drilled to make a bead. The four remaining beads on that side and the five at the back of the left side have been heated as can be seen from the vitreous shiny surface. There are traces of blue glaze that have mostly worn away, but the effects of the heat treating remain.
