These lovely matte finish heat-treated quartz crystal beads were hand cut in Afghanistan, and range in natural patterns, but are mostly clear with a brownish-beige color. 10mm diameter x 6mm thick, 63 beads per strand, 14 inches long. Beads are 10mm smooth rondelles, with a soft matte finish. Holes are .8mm. See other Afghan semi-precious stone beads listed. They design well together, as shown in the last photo, some bracelets mixed with Thai silver.
