Carnelian, Ancient Etched Coin Shape Beads, 6-10mm Diameter, Set of 6

Set of 6 ancient etched coin shape carnelian beads ranging in diameter from 6-10mm These beads were produced, and widely traded throughout Afghanistan, the Indus Valley, Mesopotamia and even as far as Ancient Egypt between 2500-1600 BCE After the hard carnelian beads were laboriously shaped, drilled, and polished, the delicate etching process involved making a paste of sodium carbonate with the juice of a plant, painting it onto the bead, and firing at precise temperatures.
