Quartz History. In ancient times, quartz was fashioned into beads or used to make talismans. It was used by the inhabitants of Mesopotamia roughly 7000 years BCE and, more recently, by the ancient Greek, Roman and Egyptian civilizations who followed. There was a belief that quartz was actually composed of super-cooled ice which had hardened ...
