History of rock crystal

While there is no clear definition of the term quartz, we will focus more on the definition of the word crystal. The term derives from the ancient Greek "krystallos" which means "ice". The same term would in turn derive from the word "kryos" which means "frost". Pliny the Elder tells of the ancient belief that attributed the creation of rock crystal to a drop in temperature so great that the crystal could no longer melt even if placed in the fire.

Archaeological excavations suggest that rock crystal was a stone known and used since prehistoric times. It would have been used to make tools, weapon tips or as a flint to start fires. Since ancient times, almost all the peoples who had known rock crystal attributed to it healing powers, even magical and supernatural.

The Greco-Romans used it to cauterize wounds by concentrating the sun's rays with a rock crystal ball. Middle Eastern civilizations have attributed to it the power to make invisible. As for the Maya, they used quartz as a divining rod to find water.
